- Synthesis and structures of substituted triphen-yl(phenyl-imino)phospho- ranes
-
Three substituted triphen-yl(phenyl-imino)phospho-ranes, namely (4-cyano-phenyl-imino)triphenyl-phospho-rane, C25H19N 2P, (I), (4-nitro-phenyl-imino)triphenyl-phospho-rane, C 24H19N2O2P, (II), and (3-nitro-phenyl-imino)triphenyl-phospho-rane, C24H19N 2O2P, (III), were synthesized as precursors for the preparation of substituted diphenyl-carbodiimides. 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 C - H...O and O...π inter-actions, forming inter-molecular dimers. Compound (III) shows disorder which involves the rotation of one of the phenyl rings of the triphenyl-phosphine group.

- Complexes of N-aryltriphenylphosphinimines with mercury(II) halides
-
The synthesis IR and 31P NMR spectra of the complexes of various N-aryltriphenylphosphinimines with some mercury dihalides as well as the corresponding phosphonium salts are reported It is shown by an X-ray crystal structure analysis of the complex of the unsubstituted phosphinimine with HgCl2 that in the solid state these complexes form dimers via two Hg...μ2 Cl...Hg bridges.
