The crystal structure described by CH2O is Indium-like structured and crystallizes in the monoclinic P2/c space group. The structure is zero-dimensional and consists of four formaldehyde molecules. C(2) is bonded in a trigonal planar geometry to two equivalent H(1) and one O(2) atom. H(1) is bonded in a single-bond geometry to one C(2) atom. O(2) is bonded in a single-bond geometry to one C(2) atom. is represented by the CIF file [CIF]
