metal-organic compounds
The crystal structure of the title compound, poly[μ2-chloro-μ2-dioxane-κ2O:O′-lithium(I)], [LiCl(C4H8O2)]n, displays a three-dimensional diamondoid network composed of Li—Cl and Li—O interactions. Each metal centre is similarly surrounded by two dioxane molecules and two chlorine atoms. The Li—O coordination is propagated along the c axis, forming a one-dimensional chain, and the three-dimensional structure is completed by Li—Cl interactions parallel to the ab plane. Principal dimensions include Li—Cl distances of 2.3115 (10) and 2.3270 (11) Å and Li—O distances of 1.9574 (10) and 1.9981 (11) Å.

The asymmetric unit of the title compound, [CaI2(C4H8O)4], at 100 K comprises half each of two independent molecules, each of which is located on a center of inversion, and in each of these, the central Ca atom is bound by two trans I atoms and four tetrahydrofuran molecules to give a distorted octahedral geometry. This compound undergoes a phase change on cooling from room temperature to 100 K, altering the space group from monoclinic P21/c to triclinic P
. This change is also accompanied by a reduction in the positional disorder of the coordinated tetrahydrofuran molecules.
