The palladium(II) and platin(II) 1, 1-dicyanoethylene-2, 2-dithiolates [(L-L)M{S2C=C(CN)2}] (M = Pd: L-L = dppm, dppe, dcpe, dpmb; M = Pt: dppe, dcpe, dpmb) were prepared either from[(L-L)MCl2] and K2[S2C=C(CN)2] or from [(PPh 3)2M{S2C=C(CN)2}] and the bisphosphane. Moreover, [(dppe)Pt{S2C=C(CN)2}]was obtained from [(1, 5-C8H12)Pt{S2C=C(CN)2}] and dppeby ligand exchange. The 1, 1-dicyanoethylene-2, 2-diselenolates[(dppe) M{Se2C=C(CN)2}] (M = Pd, Pt) were prepared from[(dppe)MCl2] and K2[Se2C=C(CN) 2]. The oxidation potentials of the square-planar palladium and platinum complexes were determined by cyclic voltammetry. The reaction of [(dcpe)Pd(S2C=O)] with TCNE led to a ligand fragment exchange and gave the 1, 1-dicyanoethylene-2, 2-dithiolate [(dcpe)Pd{S2C=C(CN) 2}] in good yield. Copyright

A series of isomalononitrile dithiolato palladium complexes, (PPh3)2Pd(i-mnt) (1), [P(OPh)3]2Pd(i-mnt) (2), (PPh3)(py)Pd(i-mnt) · CH3CN (3), (Et4N)2Pd(i-mnt)2 (4) and (Ph4As)2Pd(i-mnt)2 (5) were synthesized and characterized by elemental analysis and IR spectroscopy. The reaction between (Et4N)2Pd(i-mnt)2 (4) and (Et4N)2WS4 gave a mixed metal cluster (Et4N)2WS4Pd(i-mnt) (6). The crystallographically determined structures of 1 and 6 are reported.
