The structure described by Mn15NiO32 is trigonal omega-derived structured and crystallizes in the trigonal R-3m space group. There are three inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to one O(3), one O(5), two equivalent O(1), and two equivalent O(2) atoms to form MnO6 octahedra that share  an edgeedge with one Mn(2)O6 octahedra,  an edgeedge with one Ni(1)O6 octahedra, edges with two equivalent Mn(1)O6 octahedra, and edges with two equivalent Mn(3)O6 octahedra. In the second Mn site, Mn(2) is bonded to two equivalent O(4) and four equivalent O(2) atoms to form edge-sharing MnO6 octahedra. In the third Mn site, Mn(3) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form edge-sharing MnO6 octahedra. Ni(1) is bonded to six equivalent O(1) atoms to form NiO6 octahedra that share edges with six equivalent Mn(1)O6 octahedra. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to two equivalent Mn(1) and one Ni(1) atom. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one Mn(1), one Mn(2), and one Mn(3) atom. In the third O site, O(3) is bonded in a distorted T-shaped geometry to one Mn(1) and two equivalent Mn(3) atoms. In the fourth O site, O(4) is bonded in a distorted T-shaped geometry to one Mn(2) and two equivalent Mn(3) atoms. In the fifth O site, O(5) is bonded in a distorted T-shaped geometry to three equivalent Mn(1) atoms. is represented by the CIF card [CIF]
