The structure of new heterometallic Ru/M (M=Cu, Ni, Co, Zn) complexes investigated by combined spectroscopic and modeling studies
摘要:
This article concerns new heterometallic Ru/M (M = Cu, Ni, Co, Zn) complexes formed upon solvent extraction of [RuNO(NO2)(4)OH](2-) by trioctyl-phosphine oxide or calix[4]arene-tetraphosphine oxide. They have been characterised by IR, UV, EXAFS, and mass spectroscopies in hexane and dichloroethane solutions and by quantum mechanics calculations (PM3-tm, DFT B3LYP) in the gas phase. In these complexes, Ru and M are connected by OH and NO2 bridging groups. (C) 2002 Elsevier Science B.V. All rights reserved.
