Abstract

Twelve new zinc(II) and cadmium(II) complexes with symmetric ligands, [MCl₂((R₂N)₃PO)₂] (M = Zn, R₂N = pyrrolidinyl (1), piperidinyl (2); M = Cd, R₂N = pyrrolidinyl (3), piperidinyl (4)), and differently substituted ligands of the general formula [MCl₂(R₂N)PO(R’₂N)₂] (M = Zn or Cd; R₂N = Pyrr, Pip or Mor; R’₂N = Pyrr, Pip or Mor (5–12) have been synthesized from reaction of zinc(II) or cadmium(II) chlorides with the ligands, giving yields of 43–76%. The complexes were characterized with multinuclear (¹H, ¹³C and ³¹P) NMR, conductivity, IR spectroscopy, and X-ray analyses. Complexes 1, 3, 11, and 12 are comprised of two ligands coordinated to the metal center in a distorted monomeric tetrahedral arrangement. The P = O bond lengths of 1.490(3) (1), 1.497(4) (3), 1.480(4) (11), and 1.479(5) Å (12) are in the order observed for analogous phosphoramide complexes. The results are compared with those reported for related chalcogen counterparts.
