Crystal structure of cis-Pt[P(CH3)3]2Cl2

The molecular structure of dinuclear complexes of platinum(II). I. trans-Dichlorobistripropylphosphine-μ,μ'-dichlorodiplatinum

“…Similar bond lengths are found in cis-[PtCl2(PMe3)2] (Messmer, Amma & Ibers, 1967) where Pt-P= 2.25(1) A and Pt-C1=2.37(1) A.…”

Synthesis, Characterization, and Structures of Palladium(II) and Platinum(II) Complexes Containing N,N‐Bis(diphenylphos­phanyl)Naphthylamine

“…The coordination bond lengths of the platinum and palladium atoms (Table 2) are essentially the same and are well within the range reported for similar palladium(II) 4 – 12 and platinum(II) complexes 13 – 20 (Table 3). It is interesting to note that the Pd–P and Pt–P bond lengths are smaller than those in four‐membered ring phosphine complex cis ‐[PdCl 2 {Ph 2 PCH 2 PPh 2 }] [Pd–P = 2.234(1), 2.250(1); Pd–Cl = 2.362(1), 2.365(1) Å]37 and cis ‐[PtCl 2 (PMe 3 ) 2 ] [Pt–P = 2.315(10) Å],38 but the Pd–Cl and Pt–Cl are slightly smaller than those in these examples. These results suggest that the basic nitrogen lone pair make the phosphorus atom better donor on the coplanar to the phosphorus atom and the formation of π bond by back bonding from the metal.…”

Orthorhombic and monoclinic allotropes of cis-[PtCl2(PMePh2)2], cis-dichlorobis(methyldiphenylphosphine)platinum(II): structure analyses

“…Indeed the deviations of the cis CI-Pt-P angles from 90 ° (Table 6) show an almost linear relationship to the Pt-C1 length. The likely occurrence of a similar correlation in cis-[PtC12(PMe3) 2] (Messmer, Amma & Ibers, 1967) is a tempting subject for speculation, the Pt-CI distances differing by ca 0.02 A and the C1-Pt-P angles by ca 6 ° . Unfortunately the precision of the bond-length estimates is fairly low and the differences, though relatively large, are not statistically significant.…”
