Hf(MnSn)6 crystallizes in the hexagonal P6/mmm space group. Hf(1) is bonded to two equivalent Sn(3) and six equivalent Sn(1) atoms to form distorted edge-sharing HfSn8 hexagonal bipyramids. Mn(1) is bonded in a 6-coordinate geometry to two equivalent Sn(1), two equivalent Sn(2), and two equivalent Sn(3) atoms. There are three inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 9-coordinate geometry to three equivalent Hf(1) and six equivalent Mn(1) atoms. In the second Sn site, Sn(2) is bonded in a 6-coordinate geometry to six equivalent Mn(1) atoms. In the third Sn site, Sn(3) is bonded in a 8-coordinate geometry to one Hf(1), six equivalent Mn(1), and one Sn(3) atom.
