The crystal structure described by ZnCHO4 crystallizes in the hexagonal P6_3/m space group. Zn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form edge-sharing ZnO6 octahedra. C(1) is bonded in a trigonal planar geometry to one O(2) and two equivalent O(1) atoms. H(1) is bonded in a single-bond geometry to one O(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Zn(1) and one C(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent Zn(1) and one C(1) atom. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Zn(1) and one H(1) atom. is represented by the CIF card [CIF]
