Abstract
Three substituted triphenyl(phenylimino)phosphoranes, namely (4-cyanophenylimino)triphenylphosphorane, C25H19N2P, (I), (4-nitrophenylimino)triphenylphosphorane, C24H19N2O2P, (II), and (3-nitrophenylimino)triphenylphosphorane, C24H19N2O2P, (III), were synthesized as precursors for the preparation of substituted diphenylcarbodiimides. All three compounds display a supramolecular arrangement in which the substituted benzene rings are organized in an antiparallel fashion. The nitro group on the ring participates in CH...O and O...π interactions, forming intermolecular dimers. Compound (III) shows disorder which involves the rotation of one of the phenyl rings of the triphenylphosphine group.
