Crystal structure and Hirshfeld-surface analysis of (benzene­carbo­thio­amide-κS)bromido­bis­(tri­phenylphosphane-κP)silver(I)

The mononuclear complex exhibits a distorted tetra­hedral coordination geometry about the metal atom, arising from one S atom of the benzene­carbo­thio­amide ligand, two P atoms of two tri­phenyl­phosphane mol­ecules and one bromide ion. An intra­molecular N—H⋯Br hydrogen bond is observed and in the crystal structure, inversion dimers linked by pairs of N—H⋯Br and C—H⋯Br hydrogen bonds are observed. In addition, C—H⋯π inter­actions occur, leading to [101] chains.

Abstract

The title complex, [AgBr(C₇H₇NS)(C₁₈H₁₅P)₂], was obtained from the reaction of silver(I) bromide with benzene­carbo­thio­amide (C₇H₇NS) and tri­phenyl­phosphane (C₁₈H₁₅P) in the mixed solvent of aceto­nitrile and ethanol. The mononuclear complex exhibits a distorted tetra­hedral coordination geometry about the metal atom, arising from one S atom of a benzene­carbo­thio­amide ligand, two P atoms of two tri­phenyl­phosphane mol­ecules and one bromide ion. An intra­molecular N—H⋯Br hydrogen bond is observed and in the crystal structure, inversion dimers linked by pairs of N—H⋯Br and C—H⋯Br hydrogen bonds are observed. In addition, C—H⋯π inter­actions occur, leading to [101] chains. Hirshfeld-surface analyses are presented and discussed.

Chemical context  

Mixed-ligand complexes of Ag^I-containing phospho­rus and sulfur donor ligands have been studied and published extensively in recent years (Dennehy et al., 2007 ▸; Ruangwut & Pakawatchai, 2014 ▸) because of their potential ability to inhibit bacteria (Isab et al., 2010 ▸; Nawaz et al., 2011 ▸). Tri­phenyl­phosphane and thione ligands, which contain P and S donor atoms, respectively, are capable of forming mixed-ligand silver(I) complexes as mononuclear (Aslanidis et al., 1997 ▸) and dinuclear models (Cox et al., 2000 ▸). In this paper, we report the synthesis and structure of the mixed-ligand complex of silver(I) bromide with tri­phenyl­phosphane and benzene­carbo­thio­amide ligands.

Structural commentary  

The monomeric complex of the title compound crystallizes in the monoclinic crystal system, space group P2₁/n, and is shown in Fig. 1 ▸. The silver ion is four-coordinated exhibiting a distorted tetra­hedral environment. This deviation can be explained by P1—Ag1—P2 angle which has the highest value of 121.60 (2)° due to the steric hindrance and the repulsion between two bulky tri­phenyl­phosphane mol­ecules. The range of angles around the Ag atom of 97.338 (18)–121.60 (2)° is similar to that observed in the analogous mononuclear silver(I) complex [AgCl(C₇H₇NS)(C₁₈H₁₅P)₂] previously synthesized by us (Ruangwut & Pakawatchai, 2014 ▸), in which the angles about the metal ion are 97.298 (16)–120.053 (16)°. The Ag—S bond length of 2.6015 (8) Å is slightly longer than in [AgCl(C₇H₇NS)(C₁₈H₁₅P)₂], 2.5580 (5) Å. The Ag—P bond lengths of 2.4682 (7) and 2.4671 (6) Å for Ag1—P1 and Ag1—P2, respectively, are similar to those of the Ag—P bond lengths in [AgCl(C₇H₇NS)(C₁₈H₁₅P)₂] [2.4529 (5) and 2.4578 (5) Å], and similar to the Ag—P distances of analogous tetra­hedrally coordinated Ag^I complexes such as [Ag(NO₃)(C₂H₃N₃S)(C₁₈H₁₅P)₂] [2.4485 (6) and 2.4493 (6) Å; Wattanakanjana et al., 2014 ▸], [Ag(Htsa)(PPh₃)₃] [2.574 (7)–2.611 (6) Å; Nomiya et al., 1998 ▸] and [Ag(PPh₃)₂(bzoxtH)]·2NO₃ [2.480 (1) and 2.514 (2) Å; McFarlane et al., 1998 ▸]. An intra­molecular hydrogen bond N1—H1B⋯Br1 [3.413 (3) Å; Table 1 ▸] is found between one of the H atoms from an amine group of the benzene­carbo­thio­amide mol­ecule and the bromide ion, as depicted in Fig. 2 ▸, which also shows the inter-mol­ecular dimeric hydrogen bonds.

Supra­molecular features  

In the crystal, the dimeric inter­molecular inter­actions are generated through a crystallographic inversion center by linking through the N1—H1A⋯Br1ⁱ [3.357 (3)Å] and C17—H17⋯Br1ⁱ [3.789 (3) Å] [symmetry code: (i) 1 – x, 1 – y, 1 – z] hydrogen bonds between a pair of adjacent complex mol­ecules; these are similar to the those in the above-mentioned complex [AgCl(C₇H₇NS)(C₁₈H₁₅P)₂] (Ruangwut & Pakawatchai, 2014 ▸). There are two cyclic patterns of (8) loops formed by two pairs of N1—H1A⋯Br1 and N1—H1B⋯Br1 inter­actions and of (14) loops forming by a pair of C17—H17⋯Br1 inter­actions, as illustrated in Fig. 2 ▸. In addition, supra­molecular C—H⋯π chains (Fig. 3 ▸) are formed between the Csp ² atoms of the phenyl rings and the centroids of another phenyl ring [C22—H22⋯Cg3 = 3.782 (3) Å].

Hirshfeld surface analysis  

For the title complex, the Hirshfeld-surfaces analysis (McKinnon et al., 2004 ▸; Spackman & Jayatilaka, 2009 ▸) was generated by Crystal Explorer 3.1 (Wolff et al., 2012 ▸) and mapped over d_norm, d _e and d _i fingerprint plot (Spackman & McKinnon 2002 ▸; McKinnon et al., 2007 ▸). The contact distances to the closest atom inside (d _i) and outside (d _e) of the Hirshfeld surface analyse the inter­molecular inter­actions via the mapping of d_norm, as depicted in Fig. 4 ▸. The inter­actions are shown on the Hirshfeld surfaces with short contacts indicated in red. The corresponding fingerprint plots (Fig. 5 ▸ a–d) for Hirshfeld surfaces of the complex are shown with characteristic pseudo-symmetry wings in the upper left and lower right sides of the de and di diagonal axes that represent the overall 2D fingerprint plot and those delineated into H⋯H, H⋯Br/Br⋯H, and C⋯H/H⋯C contacts are shown in Fig. 5 ▸ a–d, respectively. The fingerprint plot of H⋯H contacts represented by the largest contribution within the Hirshfeld surfaces (60.8%) are shown as one distinct pattern with a minimum value of d _e + d_i ∼2.6 Å. The reciprocal H⋯Br/Br⋯H contacts consist of 5.4% of the total Hirshfeld surface with d _e + d_i ∼3.3 Å, exhibited by two symmetrical narrow pointed wings indicating the inter­molecular hydrogen-bond inter­actions N1—H1A⋯Br1 and C17—H17⋯Br1 in the crystal packing. The presence of C—H⋯π inter­actions on the fingerprint plot, which contribute 29.7% of overall Hirshfeld surface, are indicated by d _e + d_i ∼3.0 Å.

Synthesis and crystallization  

Silver(I) bromide (0.10 g, 0.5 mmol) was dissolved in the mixed solvent of 15 ml of aceto­nitrile and 15 ml of ethanol and then tri­phenyl­phosphane (0.27 g, 1 mmol) was added. The mixture was refluxed for 2 h at 343 K and a white precipitate was formed. After that, benzene­carbo­thio­amide (0.13 g, 1 mmol) was added and continually refluxed for 5 h. At that time, the white precipitate dissolved. The clear yellow solution was filtered and left to evaporate at room temperature. After a day, pale-yellow blocks of the title compound were filtered off and dried in vacuo. Calculated for C₄₃H₃₇AgBrNP₂S: C 61.07, H 4.37, N 1.65 and S 3.78%. Found: C 60.50, H 4.21, N 1.43 and S 3.70%.

Refinement  

Crystal data and details of structure determination are summarized in Table 2 ▸. All H atoms on carbon atoms were positioned geometrically and refined using a riding-model approximation with C—H = 0.93 Å with U _iso(H) = 1.2 U _eq(C). N-bound H atoms were found from difference maps and refined isotropically with distance restraint N—H = 0.85–0.86 Å.

Special details

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
