The crystal structure described by Ba(NO2)2 crystallizes in the orthorhombic P2_12_12_1 space group. Ba(1) is bonded in a 11-coordinate geometry to one N(1), one N(2), two equivalent O(1), two equivalent O(3), two equivalent O(4), and three equivalent O(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted bent 120 degrees geometry to one Ba(1), one O(1), and one O(4) atom. In the second N site, N(2) is bonded in a bent 120 degrees geometry to one Ba(1), one O(2), and one O(3) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Ba(1) and one N(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent Ba(1) and one N(2) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Ba(1) and one N(2) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to two equivalent Ba(1) and one N(1) atom. is represented by the CIF card [CIF]
