The structure of a linear chain compound (CH 3 ) 3 NHCdCl 3 was investigated at 355 K using a four-circle diffractometer. The structure belongs to the orthorhombic system, space group Pbnm. Unit cell dimensions are a=17.123 A, b=15.256 A, c=6.731 A and Z=8. The structure was refined by a block-diagonal least squares method. The obtained result in general agrees with the model reported previously. The
使用四圆衍射仪在 355 K 下研究直链化合物 (CH 3 ) 3 NHCdCl 3 的结构。结构属于正交晶系,空间群Pbnm。晶胞尺寸为 a=17.123 A、b=15.256 A、c=6.731 A 和 Z=8。通过块对角最小二乘法对结构进行细化。得到的结果与之前报道的模型基本一致。讨论了具有不等占有概率的三甲基铵离子的无序状态。还讨论了从室温 (\(1\times\sqrt3}\)) 相到高温 (\(2\times\sqrt3}\)) 相的相变机制。
