LiMg6C crystallizes in the orthorhombic Amm2 space group. Li(1) is bonded in a 10-coordinate geometry to two equivalent Mg(3), four equivalent Mg(1), and four equivalent Mg(2) atoms. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a single-bond geometry to two equivalent Li(1) and one C(1) atom. In the second Mg site, Mg(2) is bonded in a distorted water-like geometry to two equivalent Li(1) atoms. In the third Mg site, Mg(3) is bonded in a 2-coordinate geometry to two equivalent Li(1) atoms. In the fourth Mg site, Mg(4) is bonded in a distorted bent 150 degrees geometry to two equivalent C(1) atoms. C(1) is bonded in a 4-coordinate geometry to two equivalent Mg(1) and two equivalent Mg(4) atoms.
LiMg6C crystallizes in the orthorhombic Amm2 space group. Li(1) is bonded in a 10-coordinate geometry to two equivalent Mg(3), four equivalent Mg(1), and four equivalent Mg(2) atoms. Both Li(1)-Mg(3) bond lengths are 2.91 Å. There are two shorter (2.99 Å) and two longer (3.32 Å) Li(1)-Mg(1) bond lengths. All Li(1)-Mg(2) bond lengths are 2.92 Å. There are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a single-bond geometry to two equivalent Li(1) and one C(1) atom. The Mg(1)-C(1) bond length is 2.26 Å. In the second Mg site, Mg(2) is bonded in a distorted water-like geometry to two equivalent Li(1) atoms. In the third Mg site, Mg(3) is bonded in a 2-coordinate geometry to two equivalent Li(1) atoms.
