Abstract

The crystal structures of the gallium(II) complexes (Ph3PH)2Ga2X6 (X=Cl, Br, I) have been determined. The anions are Ga-Ga bonded species, with staggered ethane conformations; the length of the Ga-Ga bond increases only slightly along the series I>Br>Cl, although there are significant changes in the Ga-Ga stretching force constant in the order Cl>Br>I. The vibrational spectra and derived force constants are discussed, as is the splitting of thev(P-H) [andv(P-D)] mode of the cation which is related to disorder in the structure of the neighboring Ga2X62− anions.
