Studies on Transition Metal Complexes Containing the Scorpionate Ligand(Ⅱ)── Synthesis and Characterization of Zinc and Cadmium Complexes with Scorpionate Ligands

Abstract

Abstract: Two scorpionate ligands KTp^An and KTp^An were prepared and reacted with MX₂(M=Zn, Cd; X=Cl, OAc) affording some new complexes, which were characterized by elemental analysis, IRand ₁HNMR. The single crystal structure of Tp^An ZnCl has been determined by a four-circle X-ray diffractometer, which shows that the coordination environment about the Zn center is distorted tetrahedral. The crystals are monoclinic, space group P2₁ /n, with dimensions a=1.005 5(2) nm, b=1.6890(3) nm, c=1.7760(4) nm, β=102.16(3)° and Z=4, with final residuals R=0.0500 and wR=0.1202.

Key words: Poly(pyrazolyl)borate, Synthesis, Crystal structure, Hydrotris[3-(p-anisyl)pyrazol-1-yl]borate complex of zinc(Ⅱ) chloride
