Abstract

Two new bidentate phosphine dichalcogenide ligands of the type MeN(Pip₂PE)₂ [(Pip = piperidinyl; E = S (1) or Se (2)] and their cadmium(II) and mercury(II) chloride complexes MCl₂{MeN(Pip₂PE)₂} [M = Cd; E = S (3); Se (4) or M = Hg; L = S (5); Se (6)] were prepared and characterized by elemental analysis, IR, multinuclear (³¹P, ⁷⁷Se and ¹¹³Cd) NMR spectroscopy and single crystal X-ray analyses. Ligands 1 and 2 were found to adopt anti conformation structures in the solid state in which both P=E groups are trans to each other. Complexes 3-6 are comprised of one ligand coordinated in a bidentate fashion to the metal centre in a distorted tetrahedral arrangement [98.46(3)-121.24(4)°]. The P=S bond lengths of 1.999(15)-2.003(14) Å in the complex (3) are slightly elongated compared to those in free ligand [1.933(15)-1.950(14) Å]. The results are discussed and compared with closely related analogues.
