N2 - Reduction of (PPh3)2PtCl2 with hydrazine hydrate in ethanol followed by treatment with an equivalent of an alkyne gave (butynediol)bis(triphenylphosphine)platinum(0), (PPh3) 2Pt[C2(CH2OH)2] (I). According to X-ray diffraction data, the Pt atom in complex I has a square environment (Pt-C, 2.036(3) and 2.050(3) Å; Pt-P, 2.2719(8) and 2.2817(7) Å). In the coordinated butynediol, the C=C bond is lengthened(1.287(4) Å) and the angles C-CξC are reduced to 140.3(3)° and 144.6(3)°, probably because of the donation of four electrons to the Pt atom. In the crystal, complex I forms dimers stabilized by hydrogen bonds between the hydroxy groups of adjacent molecules.
