Abstract: | The crystal structures of the title compounds, Ga(S2COEt)3 (1) and In(S2COEt)3 (2) have been determined by three dimensional X-ray diffraction methods. Both compounds crystallize in the trigonal space group R with Z = 6. Cell dimensions for (1) are ahex 15.065(1) and chex 13.421(1) Å and for (2) 15.319(3) and 13.522(4) Å. Final R. and Rw values 0.044 and 0.049 for (1) and 0.040 and 0.037 for (2) for 668 and 1153 statistically significant reflections respectively.The complexes are isostructural. The metal centres are in a distorted octahedral environment, the distortion arising from the restricted bite distance of the xanthate ligands. For each compound, each xanthate moiety chelates the metal atom with similar M-S bonds. |
