ReNiO4 is beta Vanadium nitride-derived structured and crystallizes in the monoclinic C2/m space group. Re(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form ReO6 octahedra that share corners with eight equivalent Ni(1)O6 octahedra and edges with two equivalent Re(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-52°. Ni(1) is bonded to one O(1), one O(2), and four equivalent O(3) atoms to form NiO6 octahedra that share corners with eight equivalent Re(1)O6 octahedra and edges with two equivalent Ni(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-52°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to two equivalent Re(1) and one Ni(1) atom. In the second O site, O(2) is bonded in a distorted T-shaped geometry to two equivalent Re(1) and one Ni(1) atom. In the third O site, O(3) is bonded in a distorted T-shaped geometry to one Re(1) and two equivalent Ni(1) atoms.
