✦ Synopsis

The preparation and the crystal structure of the fl (brown) form of TiC13 have been re-examined. Accurate X-ray diffraction measurements on crystallographically pure samples, free from AI, allowed refinement of the structure originally proposed by the Natta school in 1958, and in particular to fix the x coordinate of the chlorine atoms in the unit cell. The X-ray characterization of products with composition (fl-TiCl3 + ~A1C13) gave no indication of the existence (suggested in the literature) of solid solutions fl-TiC13. (A1C13)0~ ~ analogous to those known for the violet modifications.

(CuI)(3)P(4)S(4) is obtained by reaction of stoichiometric amounts of CuI, P, and S in evacuated silica ampoules. The yellow compound consists of monomeric beta-P(4)S(4) cage molecules that are separated by hexagonal columns of CuI. (CuI)(3)P(4)S(4) crystallizes isotypic to (CuI)(3)P(4)Se(4) in the
