The crystal structure described by ZnC2O4 crystallizes in the monoclinic P2_1/c space group. Zn(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form corner-sharing ZnO6 octahedra. The corner-sharing octahedral tilt angles are 51°. C(1) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Zn(1) and one C(1) atom. In the second O site, O(1) is bonded in a bent 120 degrees geometry to one Zn(1) and one C(1) atom. is represented by the CIF file [CIF]
