Synthesis and Crystal Structure of Chloro(p-toluidine)4-(p-tolyl)imino-2-pentanone-3-oximato-palladium( Ⅱ ), PdCl(p-CH3C6H4NH2)(p-CH3C6H4-iai)

摘要

The title complex chloro(p-toluidine)[4-(p-tolyl)imino-2-pentanone-3-oximato]-palladium( Ⅱ ), PdCl(p-CH3C6H4NH2)(p-CH3C6H4-iai), C19H22ClN3O2Pd, (p-CH3C6H4NH2 and p-CH3C6H4-iai- are p-toluidine and the anion of 4-(p-tolyl)imino-2-pentanone-3-oximato, respectively), crystallizes in the monoclinic system, space group C2/c with a = 26.082(5), b = 13.521(3),c = 12.578(3) (A), β= 112.18(3)°, Mr = 466.25, V= 4108(2) (A)3, Dc = 1.508 g/cm3, F(000) = 1888,μ(MoKα) = 1.051 mm-1, Z = 8, the final R = 0.0368 and wR = 0.0855 for 3243 observed reflections (Ⅰ≥ 2σ(Ⅰ)). The coordination environment around Pd is a distorted PdClN3 square-plane composed of imino- and oximo-nitrogen from the Schiff base ligand of p-CH3C6H4-iai-, and amino-nitrogen from p-toluidine and chlorine atom.
