摘要
Treatment of{{(C6F5)(PPh3)Pt(mu-PPh2))(mu-H)}(2)Pt] (1) with I-2 results in a complicated reaction from which [{(C6F5)(PPh3)Pt(mu-PPh2)(mu-1)}(2)Pt] (2) is obtained. The X-ray structure and F-19 and P-31 NMR spectra are given. Density functional theory (DFT) at the B3LYP level, using the LANL2DZ basis set, provides a satisfactory description of structural, bonding, electronic and related properties of [{(CF3)(PH3)Pt(mu-PH2)(mu-H)}(2)Pt] and [{(CF3)(PH3)Pt(mu-PH2)(mu-1)}(2)Pt} model compounds. The results unambiguously justify the predictions of the through-ring bonding required by the number of framework electrons and threw light on the bonding mechanism in the "{(Pt(mu-X)(mu-PH2)}(2)Pt" (X=H, 1) nuclear framework of the compounds.
