✦ Synopsis

The title compound, [Cr(CN)~2~(C~12~H~8~N~2~)~2~][Cr(N~3~)~2~(C~18~H~12~N~4~O~2~)]·H~2~O, contains [Cr^III^(CN)~2~(phen)~2~]^+^ cations (phen is 1,10-phenanthroline) and [Cr^III^(N~3~)~2~(bpb)]^−^ anions [bpb is 1,2-bis(pyridine-2-carboxamido)benzene or N,N′-(o-phenylene)bis(pyridine-2-carboxamide)]. In the cations, the Cr^III^ atom is coordinated by two phen ligands and two cyanide ligands in a distorted octahedral geometry. In the anions, the Cr^III^ atom is coordinated by the tetradentate bpb ligand and two azide ions, forming a distorted octahedral geometry. There is one solvent water molecule per cation–anion pair, which forms hydrogen bonds to one carbonyl group of the bpb ligand and to the terminal N atom of one cyanide ligand.
