The crystal structure of [Pt(diethylenetriamine)(guanosine)](ClO4)2 has been determined by X-ray diffraction. The crystals are orthorhombic, space group P212121, with a = 12.486(6), b = 13.444(7), c = 14.678(11) Å, and Z = 4. The structure was refined by block-diagonal least-squares analysis to a conventional R factor of 0.050 and a weighted Rw = 0.045.The coordination around the platinum atom is square planar. Guanosine is bonded to platinum through N(7). The purine planar ring makes an angle of 62.7° with the platinum coordination plane. The structure is stabilized by hydrogen bonding.

The molecular and crystal structure of potassium trichloro(2,6-lutidine)platinum(II) has been determined by X-ray diffraction. The complex salt forms monoclinic crystals, a = 6.941, b = 24.301, c = 11.168 Å, β = 141.58°, Z = 4, and space group P21/c. Positional and anisotropic thermal parameters were refined by full matrix least squares calculations to R = 0.038 and Rw = 0.034.The coordination around the platinum atom is planar. The Pt—Cl bond lengths are 2.301, 2.299, and 2.302 Å and the Pt—N bond length is 2.011 Å. The 2,6-lutidine ring lies almost perpendicular to the coordination plane of the platinum atom (81.6°). The PtCl3 moieties are packed around the potassium ions, which are surrounded by four chlorine atoms at distances smaller than 3.15 Å forming a distorted tetrahedron.

The reaction of (Ph3P)2PtC2H4 with the divinyldisiloxane (CH2=CHSiMe2)2O in toluene yields Pt{(η2-H2C=CHSiMe2)2O}PPh3, which has been characterized by IR, 1H, 13C, 31P NMR and MS spectra. The crystal structure was determined by X-ray diffraction: space group C2/c, Z = 16, a = 5534.2(9), b = 842.6(2), c = 2383.1(2) pm, β = 103.73(1)°, R/Rw = 0.047/0.052. It shows a three-coordinate platinum atom with one phosphine and one sym-tetramethyldivinyldisiloxane ligand acting as a chelating bidentate η/2-ligand to give a chair conformation of the six-membered PtC2Si2O-ring system.

The reaction of K2PtCl4 with CH3—CH=CH—CH2—OH yields the complex cis-[PtCl2((CH2=CH—CH(CH3))2O)]. The crystals are triclinic, space group [Formula: see text], a = 9.420(2) Å, b = 8.359(4) Å, c = 7.837(4) Å, α = 91.10(4)°, β = 62.13(4)°, γ = 80.80(5)°, and Z = 2. The structure, solved by standard methods, has been refined anisotropically by full matrix least-squares methods to a R factor of 0.052 by use of 2441 independent observed reflections. The complex is a monomer, where both double bonds of the diolefin ether are coordinated to the platinum atom as in Zeise's salt. The usual square planar coordination of platinum(II) is completed by two chlorine atoms. The (=CH2) groups of both double bonds are found on the same side of the coordination plane. Various possible conformations of the coordinated ligand in the complex are discussed.

Reaction of [PtCl2(PMe2Ph)2] with [(PMe2Ph)2PtB10H12] generates [(PMe2Ph)2-μ-η1(Pt)- η1-(Pt')-{PMe2(C6H4)}-closo-Pt2B10H9(PMe2Ph)] in which the phenyl group of a phosphine ligand on one platinum atom exhibits ortho-cyclometallation to the second metal atom, whereas reaction of PPh3 with [(PMe2Ph)2PtB9H9Ru(pcym)] generates [(PMe2Ph)2-μ-η6(Ru)- η1(Pt)-(C6H5PPh2)-closo-PtRuB9H9] in which the phenyl group of a phosphine ligand on the platinum atom exhibits tridentate η6 coordination to the second metal atom.
