TRANS-BIS(O,O'-DIETHYL O-KAPPA(2)S,S')BIS(ISOQUINOLINE-KAPPA-N)NICKEL(II)

In (OC-6-12)-bis(O,O'-diethyl dithiophosphato-kappa(2)S, S')-bis(isoqu inoline-kappa N)nickel(II), [Ni(C4H10O2PS(2))(2)(C9H7N)(2)], a distort ed N2S4 octahedron is formed around the central Ni atom. Two O,O'-diet hyl dithiophosphate (dtp) ions act as bidentate ligands, each forming a four-membered chelate ring by coordination of its two S atoms in the equatorial plane. Two axial isoquinoline ligands are coordinated to t he metal atom through their N atoms. The Ni-S and Ni-N bond distances are 2.507 (2)-2.518 (1) Angstrom and 2.118 (3) Angstrom, respectively.
