Mn9Ga2Sn(C)3 is High-temperature superconductor-derived structured and crystallizes in the tetragonal P4/mmm space group. The structure consists of three 02329_fluka atoms inside a Mn9Ga2Sn framework. In the Mn9Ga2Sn framework, there are five inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a linear geometry to one Ga(1) and one Sn(1) atom. In the second Mn site, Mn(2) is bonded in a linear geometry to two equivalent Ga(1) atoms. In the third Mn site, Mn(3) is bonded in a linear geometry to two equivalent Sn(1) atoms. In the fourth Mn site, Mn(4) is bonded in a linear geometry to two equivalent Ga(1) atoms. In the fifth Mn site, Mn(3) is bonded in a linear geometry to two equivalent Sn(1) atoms. Ga(1) is bonded to one Mn(1), one Mn(2), and four equivalent Mn(4) atoms to form GaMn6 octahedra that share  a cornercorner with one Sn(1)Mn6 octahedra and corners with five equivalent Ga(1)Mn6 octahedra. The corner-sharing octahedral tilt angles range from 0-3°. Sn(1) is bonded to two equivalent Mn(1) and four Mn(3,3) atoms to form SnMn6 octahedra that share corners with two equivalent Ga(1)Mn6 octahedra and corners with four equivalent Sn(1)Mn6 octahedra. The corner-sharing octahedra are not tilted.
