Abstract

The title compound, [Mo(C14H9BrN2O2)O2(H2O)]·C3H7NO, has a distorted octa­hedral geometry around the Mo atom, with the two terminal oxide groups lying cis to each other. The two aromatic rings present in the mol­ecule are almost coplanar, forming a dihedral angle of 1.4 (2)°. The five-membered ring involving the metal atom is puckered, with an amplitude Q = 0.358 (2) Å and ϕ = 204.1 (6)°. In the crystal, pairs of inversion-related mol­ecules are linked by O—H⋯N hydrogen bonds. An O—H⋯O hydrogen bond connects the water ligand to the di­methyl­formamide solvent mol­ecule. The crystal packing also features π–π [centroid–centroid distance of 3.688 (2) Å] and C—H⋯O inter­actions.

Chemical context  

Aroylhydrazones are unique organic compounds characterized by the azomethine group in their mol­ecules (Sheeja et al., 2010 ▸). They exhibit a wide range of applications in the field of biology, optics, catalysis and analytical chemistry. Their broad spectrum of biological activities include anti­microbial (Sreeja et al., 2004 ▸), anti­fungal (Nfor et al., 2013 ▸), anti­viral and anti­neoplastic (Nair et al., 2014 ▸) activities. Biocidal studies reveal that hydrazones can be used as fungicides (Rai, 2006 ▸). Hydrazones are also used as DNA photocleaving agents (Pal et al., 2014 ▸) and even as a reversible photochromic system (Li et al., 2014 ▸). Hydrazone-based mol­ecular switches, metallo­assemblies and sensors have also been developed (Su & Aprahamian, 2014 ▸).graphic file with name e-71-00702-scheme1.jpg

Molybdenum is an important trace metal capable of forming various complexes with versatile organic ligands. Its flexibility in possessing a large number of stable and accessible oxidation states leads to applications in industrial and bio­logical reactions. Molybdenum complexes play a major role in catalytic activity (Maurya et al., 2014 ▸). They are employed as catalysts in olefin epoxidation (Lei & Chelamalla, 2013 ▸), reduction of di­nitro­gen to ammonia (Sengupta et al., 2015 ▸) and oxidation of secondary alcohols (Maurya et al., 2015 ▸). The biological relevance of molybdenum complexes include their application in modelling active sites of molybdoenzymes (Pramanik et al., 2004 ▸) and also their anti­bacterial (Pasayat et al., 2012 ▸), cytotoxic and anti­proliferative activities (Pasayat et al., 2014 ▸).

Structural commentary  

The title complex [Mo(C14H9BrN2O2)O2(H2O)]·C3H7NO crystallizes in the monoclinic space group P21/n. The complex adopts a distorted octa­hedral geometry around the Mo atom (Fig. 1 ▸) in which the aroylhydrazone coordinates to the metal in a tridentate manner. One di­methyl­formamide solvent mol­ecule is present without any coordination to the metal centre. Two oxygen atoms and one nitro­gen atom of the aroylhydrazone and one of the terminal oxido atoms occupy equatorial positions in the complex. The axial positions are occupied by the other terminal oxygen and the oxygen atom of the water mol­ecule. The two terminal oxido groups are cis to each other. The C8—O2 bond length [1.314 (3) Å] is close to the reported C—O single bond length (1.318 Å; Gupta et al., 2007 ▸). The Mo1—O4 and Mo1—O3 bonds of 1.693 (3) and 1.702 (2) Å, respectively, are very close to the reported Mo=O double bond [1.697 (1) Å], indicating that the complex has two Mo=O double bonds (Ebrahimipour et al., 2015 ▸).

The ligand adopts Z configurations with respect to the C7—N1 and C8—N2 bonds in the complex, which is clear from C1—C6—C7—N1 and N1—N2—C8—O2 torsion angles [9.8 (5) and −1.4 (4)°, respectively]. This configuration is similar to that of the metal-free ligand (Liu et al., 2006 ▸). The C1–C6 and C9–C14 rings make a dihedral angle of 1.4 (2)° with each other. Ring puckering analysis and least-squares plane calculations show that the Mo1/O1/C1/C6/C7/N1 ring is puckered with puckering amplitude Q = 0.358 (2)Å and ϕ = 204.1 (6)°.

Supra­molecular features  

The supra­molecular arrangement of the complex is driven by various types of classical and non-classical hydrogen-bonding inter­actions, in which O4, O5 and N2 act as acceptor atoms (Fig. 2 ▸, Table 1 ▸). There are classical O—H⋯N and O—H⋯O hydrogen-bonding inter­actions with D⋯A distances 2.891 (4) and 2.701 (4) Å respectively, and a non-classical C—H⋯O inter­action with a D⋯A distance of 3.421 (5) Å. These inter­actions connect pairs of mol­ecules along with the solvent di­methyl­formamide. The complex mol­ecule is stacked along the b axis through two different types of O—H⋯π inter­action (Fig. 3 ▸), with H–centroid distances 2.67 (4) and 2.94 (5) Å and a π–π inter­action between rings C1–C6 and C9–C14(2 − x, −y, −z) with a centroid-centroid distance of 3.688 (2) Å (Fig. 3 ▸). A view of the crystal packing along the a axis is given in Fig. 4 ▸.

Synthesis and crystallization  

The benzoyl hydrazone was synthesized by a reported procedure (Liu et al., 2006 ▸). A methano­lic solution of benzhydrazide (0.0680 g, 0.5 mmol) was refluxed with a methano­lic solution of 5-bromo­salicyl­aldehyde (0.1005 g, 0.5 mmol) continuously for 3 h. The reaction mixture was kept aside for slow evaporation at room temperature. After 2–3 days, a pale-yellow compound formed, and was washed with methanol and dried under vacuum.

The complex was synthesized by refluxing a methano­lic solution of benzoyl hydrazone (0.1595 g, 0.5 mmol) and MoCl5 (0.1362 g, 0.5 mmol) for 3 h. The brown precipitate obtained was filtered, washed with methanol, dried and recrystallized from di­methyl­formamide (yield, 0.1688g, 63%). FT–IR (KBr, cm−1) νmax: 3400, 3194, 1657, 1546, 1345, 937, 810.

Refinement  

Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. All C-bound H atoms were placed in calculated positions, guided by difference Fourier maps, with C—H bond lengths of 0.93–0.96 Å and with U iso(H) = 1.2U eq(carrier) or 1.5U eq(methyl C). The O—H distances were restrained with 1,2 and 1,3 distance restraints of 0.86 (1) and 1.36 (2) Å. Reflections (0 0 2), (1 0 1) and (Inline graphic 0 1), which were obscured by the beam stop, were omitted.

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.
