Article abstract of DOI:10.1016/0022-328X(94)87020-9

Colourless crystals of Ph3AsGaI3 (1) have been prepared by reaction of triphenylarsine with GaI3*OEt2 in diethyl ether.The structure of 1, in which the length of the As-Ga donor-acceptor bond is 2.490(2) Angstroem, has been determined by an X-ray diffraction study.In contact with the solvent phase, 1 is transformed into yellow crystals of , 2 which has been structurally characterised by Raman spectroscopy (As-I stretching at 196 cm^-1) and by X-ray diffraction.The salt 2 is the first arsenic(V) iodo complex to have been examined crystallographically; the As-I bond distance is 2.485(1) Angstroem.Key words: Gallium; Arsenic; Lewis acid-base adduct; Donor-acceptor
