The crystal and molecular structure of benzylidenimine trisulfide has been determined. Crystals are orthorhombic with a = 16.610(2), b = 9.984(6), c = 4.386(4), Z = 2 and space group P2,2,2. 773 unique reflections of positive measured intensity, recorded with a Syntex P i Automatic Diffractometer, were refined by full-matrix least-square methods to a conventional R value of 0.023. The molecule has a crystallographic two-fold axis and S-S bond lengths of 2.051(1) A. These are intermediate in length between the long inner and short outer S-S bonds of the chemically analogous tetrasulfide. The S-N and N-C bond lengths are 1.661(3) and 1.269(3), respectively. The crystal packing is determined by S-S van der Waals interaction between adjacent molecules along the c axis.

Abstract. AgCNO, orthorhombic, Cmcm, a Single-crystal diffractometer data have been collected to sin 0/2 = 0.705/~-~; the structure has been refined to R = 0.021 for 206 observed independent reflections.
