The reactivity of mer-[ReOBr3(bipy)] towards gaseous nitric oxide. The crystal, molecular and electronic structure of mer-[ReOBr3(bipy)] and [ReBr4(bipy)]
摘要:
The reactivity of mer-[ReOBr3(bipy)] (1) (bipy = bipyridine) towards gaseous nitric oxide has been investigated. The reaction of 1 with NO in bromoform has afforded only starting material, but in the presence of an excess of triphenylphosphine, the [ReBr3(NO)(bipy)] (3) has been obtained. Refluxing of 1 and PPh3 in CHBr3 has led to the isolation of [ReBr4(bipy)] (2). The complexes 1, 2 and 3 were characterised by IR, UV-Vis and magnetical measurements. Crystal and molecular structures of 1 and 2 have been determined. (C) 2003 Elsevier Ltd. All rights reserved.
