The ReOX2(met) compounds (X = Cl, Br) adopt a distorted octahedral structure in which a carboxylato oxygen lies trans to the ReO bond, whereas the equatorial plane is occupied by two cis halides, an NH2, and an SCH3 group. Coordination of the SCH3 unit creates an asymmetric center, leading to two d...
