摘要：
The compound [(PPh(3))(2)PtSe](2) has been obtained by reacting a selenide solution with (PPh(3))(2)PtCl2 and its structure has been determined by X-ray diffraction analysis. The molecular geometry of the complex consists of a four membered Pt2Se2 ring with two triphenylphosphine ligands coordinated to each platinum, giving a planar (P2Pt)(2)Se-2 arrangement. MO calculations have shown that the planar geometry is indeed slightly favoured for the neutral compound but anticipate a bent geometry for a hypothetical cationic species, in agreement with what has been found for related tellurium derivatives.
