These double chains are linked by centrosymmetric pairs of O—H...O hydrogen bonds into layers parallel to (10-1). The asymmetric unit consists of one crystallographically independent NiIIcation, one carboxylate and one DFDI ligand, as well as of one water molecule, all of them located in general positions.

Distorted Octahedral

The asymmetric unit of the title compound, [Fe(NCS)2(C12H9NO)4], consists of an FeII ion that is located on a centre of inversion, as well as two 4-benzoylpyridine ligands and one thiocyanate anion in general positions. The FeII ions are coordinated by two N-terminal-bonded thiocyanate anions and four 4-benzoylpyridine ligands into discrete complexes with a slightly distorted octahedral geometry. These complexes are further linked by weak C—H...O hydrogen bonds into chains running along the c-axis direction. Upon heating, this complex loses half of the 4-benzoylpyridine ligands and transforms into a compound with the composition Fe(NCS)2(4-benzoylpyridine)2, that might be isotypic to the corresponding MnII compound and for which the structure is unknown.

The title compound, [Ni2(C9H6O4)2(C12H8N2)2(H2O)2], is isostructural with the ZnIIanalogue. Each NiIIatom is coordinated in a distorted octahedral geometry by three O atoms from two homophthalate anions, one aqua O atom and two 1,10-phenanthroline N atoms. The two NiIIatoms are linked by two bridging homophthalate dianions into a centrosymmetric dinuclear unit. The dinuclear units are linked into one-dimensional ladder-like chains along [100] by O—H...O hydrogen bonds between the coordinated water molecules and one of the O atoms of the carboxylatomethyl group.
