K(NO2)2C crystallizes in the monoclinic C2/c space group. The structure is three-dimensional and consists of eight methane molecules and one K(NO2)2 framework. In the K(NO2)2 framework, K1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of K–O bond distances ranging from 2.75–3.15 Å. There are two inequivalent N+1.50+ sites. In the first N+1.50+ site, N+1.50+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.26 Å) and one longer (1.28 Å) N–O bond length. In the second N+1.50+ site, N+1.50+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.25 Å) and one longer (1.27 Å) N–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent K1+ and one N+1.50+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent K1+ and one N+1.50+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent K1+ and one N+1.50+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent K1+ and one N+1.50+ atom.
