Mg6BiC crystallizes in the orthorhombic Amm2 space group. The structure consists of two 02329_fluka atoms inside a Mg6Bi framework. In the Mg6Bi framework, there are four inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a distorted linear geometry to two equivalent Mg(1), two equivalent Mg(2), two equivalent Mg(3), two equivalent Mg(4), and two equivalent Bi(1) atoms. In the second Mg site, Mg(2) is bonded in a 2-coordinate geometry to two equivalent Mg(1) and two equivalent Bi(1) atoms. In the third Mg site, Mg(3) is bonded in a 12-coordinate geometry to four equivalent Mg(1) atoms. In the fourth Mg site, Mg(4) is bonded in a distorted water-like geometry to four equivalent Mg(1) and two equivalent Bi(1) atoms. Bi(1) is bonded in a 10-coordinate geometry to two equivalent Mg(4), four equivalent Mg(1), and four equivalent Mg(2) atoms.
