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=
异结构标题化合物的晶体结构。[Ga(S 2 C·NEt 2)3 ](I)和[In(S 2 C·NEt 2)3 ](II),已通过直接方法从X射线衍射数据确定并通过全矩阵精制对于1 119(I)和2 054(II)观察到的衍射仪反射,最小二乘为R 0.034和0.037。晶体为单斜晶体,空间群A 2 / a,(Z = 4),晶胞尺寸为:(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)°。离散分子的阵列代表了[M(S 2 C·NEt 2)3 ]衍生物中的新结构类型。每个分子中的三个配体是准对称的双齿,总体上具有近似D 3的分子对称性(平均Ga–S 2.436,In–S 2.597Å)。
