摘要：

Reaction of trans-[ReOCl3(PPh3)(2)] with 2-(2'-pyridyl) benzimidazole (pbiH) in methanol led to the isolation of the rhenium(III) compound [ReCl2(pbi)(PPh3)(2)] ( 1). Complex 1 could also be prepared in better yield by the reduction of [ReO4](-) with PPh3 in the presence of pbiH and hydrochloric acid. An X-ray crystallographic study showed that pbi is coordinated as a bidentate monoanionic chelate, with deprotonation of the imidazolyl NH group. The PPh3 ligands are trans to each other.
