Ti(NiN)4 crystallizes in the triclinic P-1 space group. Ti(1) is bonded in a tetrahedral geometry to one N(1), one N(2), one N(3), and one N(4) atom. There are four inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a distorted rectangular see-saw-like geometry to one N(1), one N(2), one N(3), and one N(4) atom. In the second Ni site, Ni(2) is bonded in a distorted trigonal non-coplanar geometry to one N(3) and two equivalent N(2) atoms. In the third Ni site, Ni(3) is bonded in a distorted T-shaped geometry to one N(1), one N(3), and one N(4) atom. In the fourth Ni site, Ni(4) is bonded in a rectangular see-saw-like geometry to one N(3), one N(4), and two equivalent N(1) atoms. There are four inequivalent N sites. In the first N site, N(1) is bonded to one Ti(1), one Ni(1), one Ni(3), and two equivalent Ni(4) atoms to form a mixture of distorted edge and corner-sharing NTiNi4 trigonal bipyramids. In the second N site, N(2) is bonded in a 4-coordinate geometry to one Ti(1), one Ni(1), and two equivalent Ni(2) atoms. In the third N site, N(3) is bonded to one Ti(1), one Ni(1), one Ni(2), one Ni(3), and one Ni(4) atom to form a mixture of edge and corner-sharing NTiNi4 square pyramids. In the fourth N site, N(4) is bonded in a distorted see-saw-like geometry to one Ti(1), one Ni(1), one Ni(3), and one Ni(4) atom.
