The material described by Zn(CoO2)4 crystallizes in the monoclinic Cm space group. There are four inequivalent Co sites. In the first Co site, Co(1) is bonded to one O(2), one O(7), two equivalent O(4), and two equivalent O(5) atoms to form a mixture of corner and edge-sharing CoO6 octahedra. The corner-sharing octahedral tilt angles are 56°. In the second Co site, Co(2) is bonded in a 6-coordinate geometry to one O(4), one O(8), two equivalent O(3), and two equivalent O(6) atoms. In the third Co site, Co(3) is bonded to one O(1), one O(6), two equivalent O(2), and two equivalent O(8) atoms to form a mixture of corner and edge-sharing CoO6 octahedra. The corner-sharing octahedral tilt angles range from 52-56°. In the fourth Co site, Co(4) is bonded to one O(3), one O(5), two equivalent O(1), and two equivalent O(7) atoms to form a mixture of distorted corner and edge-sharing CoO6 octahedra. The corner-sharing octahedral tilt angles are 52°. Zn(1) is bonded in a distorted pentagonal planar geometry to one O(3), two equivalent O(6), and two equivalent O(7) atoms. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Co(3) and two equivalent Co(4) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to one Co(1) and two equivalent Co(3) atoms. In the third O site, O(3) is bonded to one Co(4), two equivalent Co(2), and one Zn(1) atom to form distorted OZnCo3 tetrahedra that share corners with two equivalent O(3)ZnCo3 tetrahedra and edges with two equivalent O(7)Zn2Co3 trigonal bipyramids. In the fourth O site, O(4) is bonded in a trigonal planar geometry to one Co(2) and two equivalent Co(1) atoms. In the fifth O site, O(5) is bonded in a distorted trigonal non-coplanar geometry to one Co(4) and two equivalent Co(1) atoms. In the sixth O site, O(6) is bonded in a 5-coordinate geometry to one Co(3), two equivalent Co(2), and two equivalent Zn(1) atoms. In the seventh O site, O(7) is bonded to one Co(1), two equivalent Co(4), and two equivalent Zn(1) atoms to form distorted OZn2Co3 trigonal bipyramids that share edges with two equivalent O(3)ZnCo3 tetrahedra and edges with two equivalent O(7)Zn2Co3 trigonal bipyramids. In the eighth O site, O(8) is bonded in a trigonal non-coplanar geometry to one Co(2) and two equivalent Co(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
