Synthesis and reactivity of cyclometallated platinum (II) compounds containing [C,N,N′] terdentate ligands: Crystal structures of [PtCl{(CH3)2N(CH2)3NCH(4-ClC 6H3)}], [PtCl{(CH3)2N(CH2)3NCH(2-ClC6H3)}] and [PtCl{(CH3)2N(CH2)3NCH(3-(CH3)C6H3)}]

The reaction of compound cis-[PtCl2(dmso)2] with ligands RCHN(CH2)3NMe2 produced compounds [PtCl2{(CH3)2N(CH2)3NCHR}], which are precursors of cyclometallated platinum compounds containing a terdentate [C,N,N′] ligand.
