Abstract

In the title complexes OsII and OsIII display strong preferences for cis- and trans-S4 P2 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.
