Synthesis, properties and crystal structures of volatile dimethylgold(III) complexes based on phenyl-containing b-diketones and b-iminoketone

摘要

We have synthesized and studied volatile dimethylgold(III) complexes based on phenyl-containing bdiketones and b-iminoketone, namely (CH3)2Au(C6H5–CO–CH–CO–CH3), (CH3)2Au(bac) (1); (CH3)2Au (C6H5–CO–CH–CO–CF3), (CH3)2Au(btfa) (2); and (CH3)2Au(C6H5–CO–CH–C(NH)–CH3), (CH3)2Au(i-bac) (3). The obtained compounds were identified by elemental analysis, 1H NMR and IR-spectroscopy, and were characterized by DTA and single-crystal X-ray diffraction studies. In compounds 2 and 3, the Au atom has a square coordination environment AuC2O2 and AuC2NO, respectively.
