Whereas (COD)PtCl2 usually reacts with bidentate phosphine ligands under substitution of the COD ligand, the reaction with the newly synthesized 1,4-bis-[di(t-butylphosphino)] butane results in the insertion of COD into one Pt-P bond affording [(t-Bu)2P(CH2)4 P(t-Bu)2-(C8H12)-PtCl]+Cl- (1). 1 crystallizes in the monoclinic space group C2/c with a = 3912.8(8), b = 1765.6(3), c = 3851.3(4) pm, β = 118.36(2)°, Ζ = 24. In the cation of 1 the second C=C bond remains coordinated to the central Pt2+ ion. The square-planar coordination of Pt2+ ion is completed by a Cl ligand and the second P atom of the phosphine ligand. The inserted C-C bond is elongated to 149(5) pm with respect to the coordinating C=C bond of 133(6) pm.
