In the title compound, [Rh(C6H5N4)Cl2(C12H27P)2], the RhIIIion is chelated by the singly deprotonated 2,2′-biimidazolate (Hbim−) ligand and coordinated by two chloride ions and two tri-n-butylphosphane ligands. The chloride ions and N atoms of the Hbim−ligand lie in a plane where the sum ofX—Rh—Xangles betweencissites is 360°. The phosphane ligands occupy the sites perpendicular to the plane, completing the overall distorted octahedral coordination sphere. The complex forms a self-complementary hydrogen-bonded dimer with the inversion-related complex through N—H...N hydrogen bonds.

In the title compound, [Fe(C10H15N2O2)Cl2]·2H2O, the FeIIIion is coordinated by two N and two O atoms of the tetradentate 2-{(2-hydroxyethyl)(pyridin-2-ylmethyl)amino}ethanolate ligand and by two chloride anions, resulting in a distorted octahedral coordination sphere. The average Fe—X(X= ligand N and O atoms) and Fe—Cl bond lengths are 2.10 and 2.32 Å, respectively. In the crystal, duplex O—H...O hydrogen bonds between the hydroxyl and ethoxy groups of two neighbouring complexes give rise to a dimeric unit. The dimers are connected to the lattice water molecules (one of which is equally disordered over two sets of sites) through O—H...Cl hydrogen bonds, forming undulating sheets parallel to (010). Weak C—H...Cl hydrogen bonds are also observed.

In the title compound, [Cu(CH3COO)2(C9H8N2O)2]n, the CuIIion resides on a centre of inversion, displaying a tetragonally distorted octahedral coordination environment defined by two pairs of N and O atoms of symmetry-related 4-(1H-imidazol-1-yl)phenol ligands and the O atoms of two symmetry-related acetate ligands. The bridging mode of the 4-(1H-imidazol-1-yl)phenol ligands is associated with a very long Cu...O interactions involving the phenol O atom of the heterocyclic ligand, which creates chains extending parallel to [100]. In the crystal, the chains are arranged in a distorted hexagonal rod packing and are linkedviaC—H...O hydrogen bonds and by π–π stacking interactions involving centrosymmetrically related pairs of imidazole and phenol rings.
