Abstract
The crystal structures of the isosturctural title compounds. [Ga(S2C·NEt2)3](I) and [In(S2C·NEt2)3](II), have been determined by direct methods from X-ray diffraction data and refined by full-matrix least-squares to R 0.034 and 0.037 for 1 119(I) and 2 054 (II) observed diffractometer reflections. Crystals are monoclinic, space group A2/a, (Z= 4), with unit-cell dimensions: (I) : a= 14.862 (3), b= 10.244(2), c= 17.863(2)Å, β= 117.49(1)°:(II): a= 14.826(5), b= 10.396(5), c= 18.139(3)Å, β= 117.88(3)°. The array of discrete molecules represent a new structural type among the [M(S2C·NEt2)3] derivatives. The three ligands within each molecule are quasi-symmetric bidentate with an overall approximate D3 molecular symmetry (mean Ga–S 2.436, In–S 2.597 Å).Keywords
