ReNi2N3 crystallizes in the monoclinic C2/c space group. Re(1) is bonded to one N(1), one N(2), one N(3), and one N(4) atom to form corner-sharing ReN4 tetrahedra. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 3-coordinate geometry to one N(2) and two equivalent N(3) atoms. In the second Ni site, Ni(2) is bonded in a distorted T-shaped geometry to one N(3) and two equivalent N(2) atoms. There are four inequivalent N sites. In the first N site, N(4) is bonded in a linear geometry to two equivalent Re(1) atoms. In the second N site, N(1) is bonded in a linear geometry to two equivalent Re(1) atoms. In the third N site, N(2) is bonded in a 4-coordinate geometry to one Re(1), one Ni(1), and two equivalent Ni(2) atoms. In the fourth N site, N(3) is bonded in a rectangular see-saw-like geometry to one Re(1), one Ni(2), and two equivalent Ni(1) atoms.
