A double salt of iodo-bis-muthate: cis-aqua-iodidobis(1,10-phenanthroline)cobalt(II) tris-(1,10-phenanthroline)cobalt(II) trans-hexa-µ(2)-iodido-hexa-iodidotribismuthate(III).

In the title complex, [Co(C(12)H(8)N(2))(3)][CoI(C(12)H(8)N(2))(2)(H(2)O)][Bi(3)I(12)], conventionally abbreviated [Co(phen)(3)][CoI(phen)(2)(H(2)O)][Bi(3)I(12)], where phen is 1,10-phenanthroline, the Co(II) atom in one cation is coordinated by six N atoms from three phen ligands in an octa-hedral coordination while the Co(II) atom in the other cation is coordinated octa-hedrally by four N atoms from two phen ligands, one water O atom and one I atom. In the anion, three Bi(III) ions adopt an octa-hedral coordination constructed by six I(-) ligands. The three BiI(6) octa-hedra are fused together through trans face-sharing.

Aqua-[4-(hy-droxy-imino-meth-yl)pyridine-κN](imino-diacetato-κO,N,O')copper(II).

In the title complex, [Cu(C(4)H(5)NO(4))(C(6)H(6)N(2)O)(H(2)O)], conventionally abbreviated Cu(IDA)(4-OXPy)(H(2)O), where IDA is imino-diacetate and 4-OXPy is 4-(hy-droxy-imino-meth-yl)pyridine, the Cu(II) atom exhibits a distorted square-pyramidal coordination geometry, which is constructed from two O atoms and one N atom from a IDA ligand, one N atom from 4-OXPy ligand and one O atom from water. This mol-ecule looks like a space shuttle, the IDA ligand is its empennage (tail), and the 4-OXPy ligand is its airframe. The complexes are linked into two-dimensional supra-molecular layers parallel to (100) by three pairs of O-H⋯O hydrogen bonds. Two pairs of N-H⋯O hydrogen bonds further connect these supra-molecular layers, forming a three-dimensional supra-molecular network.
