The blue title compd., long assumed to be an olefin complex on the basis of an apparently single unresolved CN stretching band in the IR spectrum, has been identified by expt. and through DFT anal. as a s complex with the tungsten atom coordinated to one of the nitrile N centers. The previously reported data are reinterpreted in light of the new structural assignment, and spectroelectrochem. results (UV-vis, IR, EPR) are presented. on SciFinder(R)
