The compound described by Ni5ZnN4 crystallizes in the orthorhombic Pmmn space group. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a distorted trigonal planar geometry to one N(1) and two equivalent N(2) atoms. In the second Ni site, Ni(2) is bonded in a distorted tetrahedral geometry to two equivalent N(1) and two equivalent N(2) atoms. Zn(1) is bonded in an L-shaped geometry to two equivalent N(1) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded to one Ni(2), two equivalent Ni(1), and one Zn(1) atom to form NZnNi3 tetrahedra that share corners with six equivalent N(2)Ni5 square pyramids and corners with two equivalent N(1)ZnNi3 tetrahedra. In the second N site, N(2) is bonded to one Ni(2) and four equivalent Ni(1) atoms to form distorted NNi5 square pyramids that share  a cornercorner with one N(2)Ni5 square pyramid, corners with six equivalent N(1)ZnNi3 tetrahedra, and edges with two equivalent N(2)Ni5 square pyramids. is represented by the CIF file [CIF]
