WMn2P12 crystallizes in the monoclinic C2/c space group. W(1) is bonded in a 8-coordinate geometry to two equivalent P(1), two equivalent P(2), two equivalent P(3), and two equivalent P(5) atoms. Mn(1) is bonded to one P(1), one P(2), one P(3), one P(6), and two equivalent P(4) atoms to form MnP6 octahedra that share corners with four equivalent P(5)P3W tetrahedra and  an edgeedge with one Mn(1)P6 octahedra. There are six inequivalent P sites. In the first P site, P(1) is bonded in a 4-coordinate geometry to one W(1), one Mn(1), one P(4), and one P(6) atom. In the second P site, P(2) is bonded in a 4-coordinate geometry to one W(1), one Mn(1), one P(2), and one P(5) atom. In the third P site, P(3) is bonded in a distorted single-bond geometry to one W(1), one Mn(1), one P(5), and one P(6) atom. In the fourth P site, P(4) is bonded in a 4-coordinate geometry to two equivalent Mn(1), one P(1), and one P(5) atom. In the fifth P site, P(5) is bonded to one W(1), one P(2), one P(3), and one P(4) atom to form distorted PP3W tetrahedra that share corners with four equivalent Mn(1)P6 octahedra and  a cornercorner with one P(5)P3W tetrahedra. The corner-sharing octahedral tilt angles range from 54-74°. In the sixth P site, P(6) is bonded in a distorted single-bond geometry to one Mn(1), one P(1), one P(3), and one P(6) atom.
