The crystal structure described by Mg14NiC crystallizes in the orthorhombic Amm2 space group. There are seven inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 10-coordinate geometry to two equivalent Mg(2), two equivalent Mg(6), two equivalent Mg(7), and four equivalent Mg(4) atoms. In the second Mg site, Mg(2) is bonded in a 12-coordinate geometry to two equivalent Mg(1), two equivalent Mg(7), four equivalent Mg(4), and four equivalent Mg(5) atoms. In the third Mg site, Mg(3) is bonded in a distorted single-bond geometry to two equivalent Mg(7), one Ni(1), and one C(1) atom. In the fourth Mg site, Mg(4) is bonded in a 9-coordinate geometry to one Mg(4), two equivalent Mg(1), two equivalent Mg(2), two equivalent Mg(6), and two equivalent Mg(7) atoms. In the fifth Mg site, Mg(5) is bonded in a distorted L-shaped geometry to one Mg(2), one Mg(7), one Ni(1), and one C(1) atom. In the sixth Mg site, Mg(6) is bonded in a distorted single-bond geometry to one Mg(1), two equivalent Mg(4), and one Ni(1) atom. In the seventh Mg site, Mg(7) is bonded in a 7-coordinate geometry to one Mg(1), one Mg(2), two equivalent Mg(3), two equivalent Mg(4), and two equivalent Mg(5) atoms. Ni(1) is bonded in a 8-coordinate geometry to two equivalent Mg(3), two equivalent Mg(6), and four equivalent Mg(5) atoms. C(1) is bonded in a distorted pentagonal pyramidal geometry to two equivalent Mg(3) and four equivalent Mg(5) atoms. is represented by the CIF card [CIF]
