The neutral title complex, [Ni(C27H26P2)2], contains a distorted tetrahedrally coordinated Ni0 atom lying on a twofold rotation axis. The bridging propane groups of the ligands are twisted by approximately 90° with respect to each other.

The title compound, [{Fe[(SO2CH2CH2)(SCH2CH2)2N](NO)2-S,S′}NiCl{[P(C6H5)2]2(CH2)3}]·0.5CH3CN or [FeNi(C6H12NO2S3)Cl(C27H26P2)(NO)2]·0.5C2H3N, is described. There are two crystallographically distinct dimetallic complex molecules. In each molecule, the Fe atom is octahedrally coordinated, with the three S atoms and an N atom of one of the two NO ligands forming the equatorial plane; the N atoms from the second NO group and the (SO2CH2CH2)(SCH2CH2)2N ligand lie in the axial positions. The Ni atom is square pyramidally coordinated by the two bridging S atoms and the two P atoms forming the basal plane, and by the Cl atom lying in the apical position. Slight differences in the bonding modes of the NO ligands are observed for the two distinct molecules.

The structure of the neutral title complex, [{Fe[(SCH2CH2)3N](CO)2-S,S′}NiCl{[P(C6H5)2]2(CH2)3}]·CH3CN or [FeNi(C6H12NS3)Cl(C27H26P2)(CO)2]·C2H3N, is described. There are two independent complex molecules and two solvent molecules in the asymmetric unit. The Fe atoms are octahedrally coordinated; the three S atoms and a C atom of one of the two CO ligands form the equatorial plane, with the N atom of the (SCH2CH2)3N ligand and the second carbonyl C atom lying in the axial positions. The Ni atoms are square pyramidally coordinated, with the two bridging S atoms and the P atoms of the 1,3-bis(diphenylphosphino)propane ligand forming the basal plane and the Cl atom lying in the apical position.

The neutral title complex, [NiCl2(C10H24P2)] or [NiCl2(depe)], where depe is 1,2-bis(diethylphosphino)ethane, has two independent molecules in the asymmetric unit. The Ni atoms in both molecules are coordinated in a slightly distorted square-planar geometry by the two P atoms and two Cl− ions, with bond dimensions as expected. The geometry of the depe ligand in one of the molecules is typical; there is disorder in the ethyl groups in the second molecule, however, leading to some slightly distorted dimensions. The two independent molecules form discrete columns parallel to the crystallographic a axis; these `ordered' and `disordered' columns alternate along the crystallographic b and c directions, with short ClH van der Waals contacts linking four columns.
