K(NO2)3C crystallizes in the tetragonal I4_1md space group. The structure is three-dimensional and consists of eight methane molecules and one K(NO2)3 framework. In the K(NO2)3 framework, K1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of K–O bond distances ranging from 2.82–3.22 Å. There are two inequivalent N+2.33+ sites. In the first N+2.33+ site, N+2.33+ is bonded in a distorted bent 120 degrees geometry to two O2- atoms. There is one shorter (1.25 Å) and one longer (1.26 Å) N–O bond length. In the second N+2.33+ site, N+2.33+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.24 Å) and one longer (1.25 Å) N–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one N+2.33+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent K1+ and one N+2.33+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one K1+ and one N+2.33+ atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one N+2.33+ atom.
