Si(CO)2 crystallizes in the orthorhombic Immm space group. The structure is zero-dimensional and consists of four formaldehyde molecules and two SiOC clusters. In each SiOC cluster, Si(1) is bonded in a 2-coordinate geometry to two equivalent O(1) atoms. C(2) is bonded in a distorted single-bond geometry to one O(1) atom. O(1) is bonded in a trigonal planar geometry to two equivalent Si(1) and one C(2) atom.

In each SiOC cluster, Si(1) is bonded in a 2-coordinate geometry to two equivalent O(1) atoms. Both Si(1)-O(1) bond lengths are 1.95 Å. C(2) is bonded in a distorted single-bond geometry to one O(1) atom. The C(2)-O(1) bond length is 1.35 Å. O(1) is bonded in a trigonal planar geometry to two equivalent Si(1) and one C(2) atom.
