Structure of trans-diisothiocyanato(ethoxo)oxo-bis(triphenylphosphine)rhenium(V) complex

The title compound consists of [ReO(NCS)2(OEt)(PPh3)2] units in which the rhenium(V) center shows a slightly distorted octahedral coordination. The two N-coordinated NCS− groups are trans to each other, as the ReO and the ReOEt units. The ReO and ReOEt bond lengths [1.682(10) and 1.871(10) Å, respectively] and the geometry about the ethoxide oxygen atom indicate that in both cases MO ligation has a considerable degree of multiple bond.
