Thiophosphoryl chloride is a much weaker donor towards metal chlorides than phosphoryl chloride. The only addition compounds of thiophosphoryl chloride that could be isolated in a pure state are Cl3PS · SbCl5 and Cl3PS · SO3; moreover, two adducts

The structure of the phase Ti5S8 (rhombohedral) has been determined. It is based on a close packing of sulfur of the type cchh; the octahedral holes between adjacent cc sulfur layers and between adjacent hh layers are fully occupied by Ti, while the

The structure and conformation of allyldicyclopentadienyltitanium(III), (C5H5)2TiC3H5, and of some homologues substituted in the allyl ligand (mainly by methyl groups) have been investigated. Chemical arguments and infrared spectroscopy indicate that

The cyclopentadienyl(triphenylphosphine)nickel(II) halides C5H5NiPPh3X with X = Cl, Br, I, have been synthesized in good yields from nickelocene and triphenylphosphonium halides. Some chemical, physical and crystallographic properties of the complexe

The thermal behaviour of Ni3Se2 has been studied by differential thermal analysis and by high-temperature X-ray diffraction. Ni3Se2 is rhombohedral at low temperature and face-centred cubic at high temperatures. The transition between the two forms s
