ZrMn6(GaSn2)2 crystallizes in the hexagonal P6/mmm space group. Zr(1) is bonded to two equivalent Ga(1) and six equivalent Sn(2) atoms to form edge-sharing ZrGa2Sn6 hexagonal bipyramids. Mn(1) is bonded in a 6-coordinate geometry to two equivalent Ga(1), two equivalent Sn(1), and two equivalent Sn(2) atoms. Ga(1) is bonded to one Zr(1) and six equivalent Mn(1) atoms to form corner-sharing GaZrMn6 hexagonal pyramids. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 6-coordinate geometry to six equivalent Mn(1) atoms. In the second Sn site, Sn(2) is bonded in a 9-coordinate geometry to three equivalent Zr(1) and six equivalent Mn(1) atoms.
