The structure described by H(CO)2 is Indium-like structured and crystallizes in the monoclinic Pm space group. The structure is zero-dimensional and consists of eight methanol with formaldehyde molecules. There are two inequivalent C sites. In the first C site, C(1) is bonded in a single-bond geometry to one O(4) atom. In the second C site, C(4) is bonded in a single-bond geometry to one O(2) atom. H(1) is bonded in a linear geometry to one O(2) and one O(4) atom. There are two inequivalent O sites. In the first O site, O(2) is bonded in a bent 120 degrees geometry to one C(4) and one H(1) atom. In the second O site, O(4) is bonded in a bent 120 degrees geometry to one C(1) and one H(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
