The structure described by Mg2BN2Cl crystallizes in the orthorhombic Pbca space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 6-coordinate geometry to one N(2), two equivalent N(1), and three equivalent Cl(1) atoms. In the second Mg site, Mg(2) is bonded in a 5-coordinate geometry to one N(1), two equivalent N(2), and two equivalent Cl(1) atoms. B(1) is bonded in a linear geometry to one N(1) and one N(2) atom. There are two inequivalent N sites. In the first N site, N(1) is bonded to one Mg(2), two equivalent Mg(1), and one B(1) atom to form a mixture of distorted edge and corner-sharing NMg3B tetrahedra. In the second N site, N(2) is bonded to one Mg(1), two equivalent Mg(2), and one B(1) atom to form corner-sharing NMg3B tetrahedra. Cl(1) is bonded in a 5-coordinate geometry to two equivalent Mg(2) and three equivalent Mg(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
