Abstract
The reaction of equimolar amounts of trans-[ReOCl3(PPh3)2] and 2-aminobenzimidazole in acetone containing 1% water led to the isolation of trans-[ReO(OH)Cl2(PPh3)2]. The product has been characterized by infrared spectroscopy and X-ray crystallography. The hydroxo group is coordinated trans to the oxo group, with the respective bond lengths Re–OH = 1.911(3) and Re=O = 1.815(3) Å.
