The material described by Ni3AgP3(HO6)2 crystallizes in the monoclinic C2/c space group. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded to one O(3), one O(4), one O(5), one O(6), and two equivalent O(1) atoms to form NiO6 octahedra that share corners with two equivalent P(2)O4 tetrahedra, corners with four equivalent P(1)O4 tetrahedra,  an edgeedge with one Ni(1)O6 octahedra, and  an edgeedge with one Ni(2)O6 octahedra. In the second Ni site, Ni(2) is bonded to two equivalent O(2), two equivalent O(5), and two equivalent O(6) atoms to form NiO6 octahedra that share corners with two equivalent P(2)O4 tetrahedra, corners with four equivalent P(1)O4 tetrahedra, and edges with two equivalent Ni(1)O6 octahedra. Ag(1) is bonded in a 4-coordinate geometry to four equivalent O(3) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(2), one O(3), and one O(6) atom to form PO4 tetrahedra that share corners with two equivalent Ni(2)O6 octahedra and corners with four equivalent Ni(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 39-57°. In the second P site, P(2) is bonded to two equivalent O(4) and two equivalent O(5) atoms to form PO4 tetrahedra that share corners with two equivalent Ni(2)O6 octahedra and corners with four equivalent Ni(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 53-58°. H(1) is bonded in a linear geometry to one O(2) and one O(4) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Ni(1) and one P(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Ni(2), one P(1), and one H(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Ni(1), two equivalent Ag(1), and one P(1) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one Ni(1), one P(2), and one H(1) atom. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to one Ni(1), one Ni(2), and one P(2) atom.
