The reaction between CR)>n (R = ^tBu, Ph) and the appropriate mononuclear palladium or platinum substrate affords mononuclear derivatives of the type CR)L2> (M = Pd, Pt; R = ^tBu, Ph; L = PPh3, dppe).Polynuclear (NBu4)2CPh)4> (X = F, Cl; R = Ph, ^tBu) complexes are obtained by reaction between (NBu4)2 (X' = Cl, X = F; X' = I, X = Cl) and CR)>n (Pt:Ag ratio 1:2).Similar heterometallic derivatives Q2CR)4> (Q = PMePh3, NBu4; M = Ag, Cu; R = Ph, ^tBu) can be prepared by reaction of Q2CR)2> with AgCl or CuCl (Pt:M ratio 1:1).The structure of (NBu4)2CPh)4>*4CH2Cl2 has been determined by X-ray diffraction.
