Abstract

MgCl2 crystallizes in the orthorhombic Pmma space group. The structure is two-dimensional and consists of one MgCl2 sheet oriented in the (0, 0, 1) direction. Mg2+ is bonded to six Cl1- atoms to form a mixture of edge, face, and corner-sharing MgCl6 octahedra. The corner-sharing octahedral tilt angles are 50°. There are two shorter (2.38 Å) and four longer (2.67 Å) Mg–Cl bond lengths. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in an L-shaped geometry to two equivalent Mg2+ atoms. In the second Cl1- site, Cl1- is bonded in a 4-coordinate geometry to four equivalent Mg2+ atoms.
