Crystal structure of [tBuMgCl]2[MgCl2(Et2O)2]2

ABSTRACT: The crystal structure of [tBuMgCl]2[MgCl2(Et2O)2]2 features an Mg4Cl6 open-cube cluster with both four- and six-coordinate Mg2+ ions. The Cl− ions adopt bridging positions. Inter­molecular C—H⋯Cl hydrogen bonds link adjacent units of the title compound into chains extending parallel to [010]. The title compound, di-μ3-chlorido-tetra-μ2-chlorido-tetra­kis­(diethyl ether-κO)bis­(1,1-di­methyl­eth­yl)tetra­magnesium, [Mg4(C4H9)2Cl6(C4H10O)4], features an Mg4Cl6 open-cube cluster. The two four-coordinate Mg2+ ions show an almost tetra­hedral coordination, whereas the two six-coordinate Mg2+ ions have their ligands in an octa­hedral environment. The Mg—Cl bond lengths differ depending on the coordination number (2 or 3) of the bridging μ-Cl− ligands. There are few comparable structures deposite
