在较早的研究中,对氯铜矿的晶体结构Cu 2Cl(OH)3或CuCl2.3Cu(OH)2的坐标进行了修正。每个Cu原子有四个最近的OH邻居(平均Cu-OH距离2.01 A), 另外还有两个邻居完成了扭曲的八面体配位群。对于一半的Cu原子,这些是一个OH(在2.36 A处)。 和一个Cl(在2.75 A.), 而对于其余的,两个Cl(在2.76 A.)。 比较了CuCl_2、Cu_2Br(OH)_3和Cu_2Cl(OH)_3的结构。
The co-ordinates assigned in an earlier study of the crystal structure of atacamite, Cu2Cl(OH)3 or CuCl2.3Cu(OH)2, have been revised. Each Cu atom is shown to have four nearest OH neighbours (mean Cu—OH distance 2.01 A.), and in addition two more neighbours completing distorted octahedral co-ordination groups. For one-half of the Cu atoms these are one OH (at 2.36 A.) and one Cl (at 2.75 A.), and for the remainder, two Cl (at 2.76 A.). A comparison is made of the structures of CuCl2, Cu2Br(OH)3 and Cu2Cl(OH)3.
