The Re atom is six-coordinate in a distorted octahedral environment. The two triphenylphosphine ligands are arranged trans to each other and there is a methoxy group in the position trans to the phenylimido group. The Re-- NPh distance is 1.744 (4),~, and the NCS ligands are coordinated via the N atom. Comment The title compound, (1), consists of discrete monomeric molecules. An ORTEPII plot (Johnson, 1976) together with the atomic numbering scheme is shown in Fig. 1.
