The title compound, lithium magnesium chloride heptahydrate, LiCl.MgCl(2).7H(2)O, was analyzed in 1988 by powder X-ray diffraction [Emons, Brand, Pohl & Köhnke (1988). Z. Anorg. Allg. Chem. 563, 180-184] and a monoclinic crystal lattice was determined. In the present work, the structure was solved from single-crystal diffraction data. A trigonal structure was found, exhibiting a network structure of Mg(H(2)O)(6) octahedra and Li(H(2)O)Cl(3) tetrahedra connected by H...Cl hydrogen bonds. The Li(H(2)O) unit is coordinated by distorted edge-connected Cl(-) octahedra.
标题化合物七水合氯化锂镁（LiCl·MgCl₂·7H₂O）于1988年通过粉末X射线衍射进行了分析[埃蒙斯、布兰德、波尔和克恩克（1988年）。《无机及普通化学杂志》563，180 - 184]，并确定了单斜晶格。在本工作中，从单晶衍射数据解析了其结构。发现其为三角结构，呈现出由H…Cl氢键连接的Mg(H₂O)₆八面体和Li(H₂O)Cl₃四面体的网络结构。[Li(H₂O)]⁺单元由扭曲的边相连的Cl⁻八面体配位。
