Crystal Structures and Multiple Bonding in trans-Pt[P(C₂H₅)₃]₂Cl₂ and trans-Pt [P(C₂H₅)₃]₂Br₂

Structure of the mixed-valence compound dipotassium tribromo(pyridine)platinate(II) pentabromo(pyridine)platinate(IV) dihydrate

“…in good agreement with those found for other Pt compounds (Keller et al, 1981;Ryan & Rundle, 1961;Bokii & Kukina, 1965;Russell, Tucker & Whittaker, 1975;Messmer & Amma, 1966;Mblanson, Rochon & Hubert, 1979;M61anson, Hubert & Rochon, 1975). The Pt-N distance [2.09 (4) A] is also normal (Keeton, Mason & Russell, 1971;Colamarino & Orioli, 1975;Caira & Nassimbeni, 1975;Thiele & Wagner, 1978;Meester, Olie, Sint & Schenk, 1975).…”

The crystal structure and absolute configuration of the complex (+)-trans-{PtCl[SiMe-(1-C10H7)Ph](PMe2Ph)2}

“…The Pt-P lengths do not differ significantly from the mean of 2.299 g, which is in good agreement with other Pt tt trans phosphine distances, e.g. 2.300 A in trans- [Pt(PEt3)zClz] (Messmer & Amma, 1966) The angles subtended at the Si atom by its substituents are less than the corresponding angles in the parent silane (1-CloHv)PhMeSiH (all near to 110°). PhMeSiH and also in (l-naphthylphenylmethylsilyl)-benzyl p-bromobenzoate (Nyburg, Brook, Pascoe & Szymafiski, 1972), particularly in the relative shortness of C(13)-C(14).…”

Tripotassium cis-dichloro(hydrogendisulfito)platinate(II) K3[Pt{(SO3)2H}Cl2]. A case of an extremely short hydrogen bond O...H...O

“…Again, a similar situation is observed for the Pt-P bonds in trans-diphosphineplatinum(II) complexes, e.g. trans-Pt(PEt3)2C12 (Messmer & Amma, 1966). Otherwise a structural trans influence of the sulfito ligand is documented only in a few cases of octahedral cobalt(III) complexes.…”
