Differentiation of isomeric coordination geometries by metal valence: a structural study of its origin in [Os(EtSCS2)2(PPh3)2]z(z= 0 and 1+)
Abstract
In the title complexes OsII and OsIII display strong preferences for cis- and trans-S4P2 geometries respectively; structural parameters of the cis-OsII, trans-OsII and trans-OsIII isomers have revealed that back-bonding and steric crowding within the Os(PPh3)2 fragment are the primary controlling factors.
