Synthesis of o-nitrophenylplatinum(IV) complexes; crystal and molecular structure of dichlorobis(2=nitrophenyl=C′O)platinum(IV)

Abstract

The reactions between [Pt{2-C₆H₄N(O)O}₂] and halogens or MeI give complexes [Pt{2-C₆H₄N(O)-O}₂X₂][X = Cl (1), Br, or I] or [Pt{2-C₆H₄N(O)O}₂Me(I)], respectively. Complex (1) reacts with bidentate ligands L–L giving [Pt(2-C₆H₄NO₂)₂Cl₂(L–L)](L–L = 1.10-phenanthroline or 2,2′-bipyridyl). The crystal structure of (1) shows octahedral co-ordination with the halogen atoms mutually trans and the chelating o-nitrophenyl ligands mutually cis.
