The material structure described by Co3ZnO7 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to one O(4), two equivalent O(1), and two equivalent O(2) atoms to form distorted CoO5 trigonal bipyramids that share corners with three equivalent Zn(1)O5 square pyramids, corners with two equivalent Co(2)O5 trigonal bipyramids,  an edgeedge with one Co(2)O5 trigonal bipyramid, and edges with two equivalent Co(1)O5 trigonal bipyramids. In the second Co site, Co(2) is bonded to one O(3), two equivalent O(1), and two equivalent O(2) atoms to form distorted CoO5 trigonal bipyramids that share  a cornercorner with one Zn(1)O5 square pyramid, corners with four equivalent Co(1)O5 trigonal bipyramids,  an edgeedge with one Zn(1)O5 square pyramid, and edges with two equivalent Co(1)O5 trigonal bipyramids. Zn(1) is bonded to one O(3), two equivalent O(1), and two equivalent O(4) atoms to form ZnO5 square pyramids that share  a cornercorner with one Co(2)O5 trigonal bipyramid, corners with six equivalent Co(1)O5 trigonal bipyramids, and  an edgeedge with one Co(2)O5 trigonal bipyramid. There are four inequivalent O sites. In the first O site, O(3) is bonded in a bent 120 degrees geometry to one Co(2) and one Zn(1) atom. In the second O site, O(4) is bonded in a bent 150 degrees geometry to one Co(1) and one Zn(1) atom. In the third O site, O(1) is bonded to one Co(2), two equivalent Co(1), and one Zn(1) atom to form a mixture of distorted edge and corner-sharing OZnCo3 trigonal pyramids. In the fourth O site, O(2) is bonded in a trigonal non-coplanar geometry to one Co(2) and two equivalent Co(1) atoms. is represented by the CIF card [CIF]
