[Pt(Cl)2(PEt3)2]. Further reaction of [Pt(CSe3)(PMe2Ph)2] with [M(CO)6] (M = Cr, W, Mo) yielded bimetallic species of the type [Pt(PMe2Ph)2(CSe3)M(CO)5] (M = Cr, W, Mo). The dimeric triselenocarbonate complexes [M(CSe3)(η5-C5Me5)}2] (M = Rh, Ir) and [M(CSe3)(η6-p-MeC6H4iPr)}2] (M = Ru, Os) have been synthesised from the appropriate transition metal dimer starting material. The triselenocarbonate ligand is

Pt1–N1 distance is 2.050(5) Å. The N1–N2 distance is 1.421(6) Åwhile the N2–C5 and C5–O1 distances are 1.273(7) and 1.314(7) Å, respectively. Complexes 1–5 show sensitivity towards chlorinated solvents (CH2Cl2, CHCl3) under photolysis conditions, forming the corresponding cis-platinum bis(phosphine) dichloride complexes; the same products are formed in a slower thermal reaction with 2 and 5.

Abstract Reaction of CS2 with NH3(liq) gives the (CS3)2− dianion which undergoes in situ reaction with MCl2(PR3)2 to give M(PR3)2(CS3). X-ray analysis of four examples (M=Pt, PR3=PMe3, PMe2Ph, PPh3, dppp) reveals square planar coordination with the [CS3]2− dianion being effectively in the same plane as the coordination sphere. The first example of a [CSeS2]2− complex is also reported.
