Abstract: 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.
