Hemilability and structural considerations in complexes of platinum(II) comprising bis(diphenylphosphanyl)methane monoxide, monosulfide, and monoselenide

Abstract

The structure of a platinum(II) complex containing (R)-(dimethylamino)ethylnapthyl and bis(diphenylphosphanyl)methane monosulfide ligands, namely, {(R)-1-[1-(dimethylamino)ethyl]napthyl-κ2 N,C 2}[(diphenylphosphanylmethyl)diphenylphosphine sulfide-κ2 P,S]platinum(II) hexafluoridoantimonate dichloromethane monosolvate, [Pt(C14H16N)(C25H22P2S)][SbF6]·CH2Cl2, was determined. The structural features are compared with analogous platinum bis(diphenylphosphanyl)methane monoxide [dppm(O)] and bis(diphenylphosphanyl)methane monoselenide [dppm(Se)] complexes in relation to their potential hemilability and stereochemical nonrigidity.
