【Abstract】 Two scorpionate ligands KTp An and KTp An were prepared and reacted with MX 2(M=Zn, Cd; X=Cl, OAc) affording some new complexes, which were characterized by elemental analysis, IR and \{ 1H NMR\}. 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 P2 1/n , with dimensions a= 1.00 5 5(2) nm, b = 1.689 0(3) nm, c = 1.776 0(4) nm, β =102.16(3)° and Z=4, with final residuals R = 0.050 0 and wR = 0.120 2.更多还原
