Synthesis and Crystal Structure of(2,2,6,6-Tetramethyl-3-imino-4-heptene-5-onata)dimethylgold(III)

摘要

A novel volatile complex of gold(III),(CH3)2Au[C(CH3)3C(NH)CHC(O)C(CH3)3],was synthesized and studied by the elemental analysis,IR spectroscopy,DTA,and X-ray diffraction analysis.Two crys-tallographically independent gold complexes have different orientation in a unit cell.The Au atoms in both complexes exhibit slightly distorted square coordination involving the O and N atoms of the(3-iminoketonate ligand and two C atoms of the methyl groups.The average lengths of the bonds Au-CH3,Au-O,and Au-N are 2.034,2.086,and 2.070 A,the chelate angle NAuO being 89.4°.The gold complexes are packed in stacks with the distances Au…Au 3.494 A.
