C2N2O
C2N2O is the chemical formula representing compounds composed of two carbon atoms, two nitrogen atoms, and one oxygen atom. It does not designate a single, well-characterized molecule; instead, several constitutional isomers with this formula have been proposed or detected in specialized studies. Because C2N2O encompasses multiple possible connectivities, the exact structural identity is typically specified by a systematic name or a structural diagram in literature or databases.
Reliable data on C2N2O are limited. Much of the information comes from theoretical calculations or from transient
Physical properties such as melting and boiling points or densities are not established due to the lack
