Hydrothermal synthesis and structure of [Co(imi)6] · (NBA)2 · 2H2O (imi = imidazole, NBA = 4-nitrobenzoic acid)
A novel cobalt complex [Co(imi)6] · (NBA)2 · 2H2O (1), (imi = imidazole, NBA = 4-nitrobenzoic acid) has been hydrothermally synthesized and characterized by physical measurements and single-crystal X-ray diffraction techniques. The complex is triclinic, space group P1, with a = 8.0057(16), b = 9.2327(18), c = 13.618(3) Å, α = 95.89(3), = 101.27(3), = 103.71(3), V = 947.2(3) Å3, Z = 1. In 1, the cobalt(II) ion is octahedral, coordinated by six nitrogen atoms from imidazole rings. An extensive three-dimensional supramolecular structure is formed via O-H ··· N and O-H ··· O hydrogen bonds between [Co(imi)6]2+ cations, NBA anions and water molecules, and - interactions between NBA molecules.
