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

The structure of a platinum(II) complex containing (R)-(dimethylamino)ethylnapthyl and bis(diphenylphosphanyl)methane monosulfide ligands, namely, {(R)-1-1-(dimethylamino)ethyl]napthyl-κ²N,C²}(diphenylphosphanylmethyl)diphenylphosphine sulfide-κ²P,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.
