Spectroscopic and crystallographic studies of phosphino adducts of gallium(III) iodide
The solid state structures of the compounds GaI 3 *PPh 3 and Ga 2 I 6 *dppe ( dppe = 1,2-bis(diphenylphosphino)ethane ) have been determined. For the former, in which the GaI 3 P core has C 3v symmetry, the structure is trigonal, with a = 14.961(2) Å, c = 16.509(3) Å, V = 3199.5(4) Å 3 , Z = 6, spac...
