Crystal structure of aqua­bis­(hepta­fluoro­butano­ato-κO)(1,10′-phenanthroline-κ² N,N′)copper(II)

The mol­ecular structure of a mononuclear Cu^II complex coordinated by hepta­fluoro­butanoic acid, 1,10-phenanthroline and a water mol­ecule is described.

Abstract

The title compound, [Cu(C₄F₇O₂)₂(C₁₂H₈N₂)(H₂O)], is mononuclear and contains a penta­coordinated Cu^II ion. The geometry of Cu^II ion can be described as distorted square-pyramidal with two O atoms of two butano­ate anions and two N atoms of the o-phenanthroline ligand occupying the basal plane, and a water O atom located at the axial position. In the crystal, C—H⋯(O,F) and O—H⋯(O,F) hydrogen bonds and π–π inter­actions [centroid-to-centroid distance 3.533 (2) Å] link the mol­ecules into a three-dimensional supra­molecular structure.

Chemical context  

Over the past decades, vast efforts have been dedicated to the rational design and synthesis of metal-carboxyl­ate coordination polymers due to their potential applications in medicine, electronics, magnetism, catalysis, gas storage, etc (Ahmad et al., 2014 ▸; Patel et al., 2013 ▸). In addition, metal–o-phenanthroline complexes and their derivatives have attracted much attention because of their unusual features (Ma et al., 2004 ▸; Bi et al., 2004 ▸; Wall et al., 1999 ▸; Naing et al., 1995 ▸). This work reports a new copper coordination complex, [Cu(C₄F₇O₂)₂(C₁₂H₈N₂)(H₂O)], resulting from the reaction of hepta­fluoro­butanoic acid and Cu^II ions in the presence of o-phenanthroline.

Structural commentary  

The neutral complex [Cu(C₄F₇O₂)₂(C₁₂H₈N₂)(H₂O)] is composed of a central Cu^II ion, coordinated by two oxygen atoms (O1 and O3) of two butano­ate anions, an oxygen atom (O5) of the water mol­ecule, and two nitro­gen atoms (N1 and N2) of the N,N′–chelating o–phenanthroline ligand (Fig. 1 ▸). Selected geometric parameters are presented in Table 1 ▸. The coordination about the Cu^II ion is better described as a square-pyramid. The geometry parameter τ, which is defined as τ = (β − α)/60, is applicable to five-coordinate structures within the structural continuum between trigonal–bipyramidal and tetra­gonal or rectangular pyramidal. For perfect tetra­gonal symmetry, τ is zero, and for perfect trigonal–bipyramidal geometry, τ becomes 1.0 (Addison et al., 1984 ▸). In the title compound, the largest angles within the four atoms N1, N2, O2, O3 are β = 169.16 (12)° for O1–Cu1—N2, and α = 156.71 (11)° for N1—Cu1—O3. Thus, τ is 0.21, indicating a 79% rectangular pyramidal geometry.

The Cu—O bonds [1.942 (3) and 1.980 (3) Å] in the quadrilateral plane are shorter than the apical position [2.173 (3) Å]. The mean Cu—N(phen) distance of 2.043 Å and the bite angle N1—Cu1—N2 of 81.75 (12)° are close to the corresponding values observed in related copper–o-phenanthroline compounds (Beghidja et al., 2014 ▸; Awaleh et al., 2005 ▸). The cisoid bond angles are in the range 81.75 (12)–96.11 (11)°, and transoid ones are 156.71 (11)°, and 169.16 (12)° exhibiting substantial deviations from 90 and 180° for a square. These are consistent with literature values (Jing et al., 2011 ▸). An intra­molecular C1—H1⋯O1 hydrogen bond occurs.

Supra­molecular features  

In the crystal, inter­molecular O—H⋯O, C—H⋯O and C—H⋯F hydrogen bonds (Table 2 ▸) link the mol­ecules into a three-dimensional network (Fig. 2 ▸). The oxygen atom (O5) of the water mol­ecule acts as a hydrogen-bond donor, via atoms H5A and H5B, to oxygen atom O3 of one coordinating carboxyl­ate group (−x + , −y + , −z) and to the dangling oxygen atom O2 of the other coordinating carboxyl­ate group (−x + , −y + , −z), thus enclosing centrosymmetric (16) ring motifs (Bernstein et al., 1995 ▸) running parallel to the b-axis direction (Fig. 3 ▸). In addition, C—H⋯F and O—H⋯F hydrogen bonds are formed, (C6—H6⋯F4 and O5—H5B⋯F10; Table 2 ▸; Fig. 3 ▸); the H⋯F distances are comparable with those reported for C—H⋯F inter­actions (2.44–2.90 Å; Dunitz & Taylor et al., 1997 ▸, Bianchi et al., 2003 ▸; Lee et al., 2000 ▸).

Representative O—H⋯O, C—H⋯O and C—H⋯F and π–π stacking inter­actions viewed along the c axis are drawn as dotted lines.

In the crystal, the packing appears to be influenced by π–π stacking inter­actions between o-phenanthroline ring systems of neighboring mol­ecules, with the distance between the centroids of the N1/C1–C4/C12 and C4–C7/C11/C12 rings being 3.533 (2) Å. (Fig. 4 ▸). The shortest Cu⋯Cu distance in the supra­molecular structure is 7.845 Å.

Synthesis and crystallization  

Cu(ClO4)·6H₂O in methanol (0.076 mmol, 0.19 g) was added to a solution of o-phenanthroline (0.076 mmol, 0.14 g) and hepta­fluoro­butanoic acid (0.0160 mmol, 0.1ml) in methanol (7 ml). Afterwards the obtained transparent blue solution was left to evaporate slowly in the air at ambient temperature and after two weeks, X-ray quality crystals appeared as blue plates. They were filtered off, washed with diethyl ether and dried in the air. Yield: 46 mg, 86%.

Refinement  

Crystal data, data collection and structure refinement details are summarized in Table 3 ▸. C-bound H atoms were placed in calculated positions and refined as riding with C—H = 0.95 Å and U _iso(H) = 1.2U _eq(C). The coordinates of the water H atoms were refined, and U _iso(H) was set to be 2U _eq(O). One of the hepta­fluoro­butano­ate groups is disordered over two sets of sites in a 0.705 (9):0.955 (9) ratio. Atoms associated with the disorder were refined with isotropic displacement parameters.

Special details

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

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
