The structure described by ZnH8(CO3)2(CO)2 is Indium-derived structured and crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of eight formaldehyde molecules and four ZnH8(CO3)2 clusters. In each ZnH8(CO3)2 cluster, Zn(1) is bonded in an octahedral geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. C(1) is bonded in a distorted single-bond geometry to one O(3) atom. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(1) atom. In the third H site, H(3) is bonded in a single-bond geometry to one O(2) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one O(2) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Zn(1), one H(1), and one H(2) atom. In the second O site, O(2) is bonded in a distorted water-like geometry to one Zn(1), one H(3), and one H(4) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Zn(1) and one C(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
