The structure described by CsCH(NO)2 crystallizes in the monoclinic P2_1/c space group. Cs(1) is bonded in a 8-coordinate geometry to one N(2), two equivalent N(1), two equivalent O(2), and three equivalent O(1) atoms. C(1) is bonded in a trigonal planar geometry to one N(1), one N(2), and one H(1) atom. There are two inequivalent N sites. In the first N site, N(1) is bonded in a bent 120 degrees geometry to two equivalent Cs(1), one C(1), and one O(2) atom. In the second N site, N(2) is bonded in a bent 120 degrees geometry to one Cs(1), one C(1), and one O(1) atom. H(1) is bonded in a single-bond geometry to one C(1) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to three equivalent Cs(1) and one N(2) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Cs(1) and one N(1) atom. is represented by the CIF file [CIF]
