The material structure described by K3BN2 crystallizes in the monoclinic P2_1/c space group. There are three inequivalent K sites. In the first K site, K(1) is bonded in a 6-coordinate geometry to two equivalent B(1), two equivalent N(1), and two equivalent N(2) atoms. In the second K site, K(2) is bonded in a 4-coordinate geometry to two equivalent N(1) and two equivalent N(2) atoms. In the third K site, K(3) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form corner-sharing KN4 tetrahedra. B(1) is bonded in a linear geometry to two equivalent K(1), one N(1), and one N(2) atom. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted single-bond geometry to two equivalent K(1), two equivalent K(2), two equivalent K(3), and one B(1) atom. In the second N site, N(2) is bonded in a distorted single-bond geometry to two equivalent K(1), two equivalent K(2), two equivalent K(3), and one B(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
