Bis(1,10-phenanthroline-²N,N')-bis(cyanido-C)cobalt(III) bis(azido-¹N)[1,2-bis(pyridine-2-carboxamido)benzene-⁴N]chromate(III) monohydrate

Abstract: The structure of the title compound, [Co(C₁₂H₈N₂)₂(CN)₂][Cr(C₁₈H₁₂N₄O₂)(N₃)₂]·H₂O, comprises a [Co^III(phen)₂(CN)₂]⁺ (phen = 1,10-phenanthroline) cation, a [Cr^III(bpb)(N₃)₂]^- [bpb^2- = 1,2-bis(pyridine-2-carboxamido)benzene] anion and an uncoordinated water molecule. The Co and Cr ions are six-coordinated by N₄C₂ and N₆ sets, respectively, yielding distorted octahedral coordination geometries. The [Co^III(phen)₂(CN)₂]⁺ and [Cr^III(bpb)(N₃)₂]^- ions and water molecules are connected by - interactions [shortest distance 3.376 (2) Å] and O-HO, O-HN, C-HO and C-HN hydrogen bonds into a three-dimensional supramolecular network structure.
