The material structure described by K2MnN4 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 8-coordinate geometry to one N(3), two equivalent N(1), two equivalent N(2), and three equivalent N(4) atoms. In the second K site, K(2) is bonded in a 7-coordinate geometry to one N(4), two equivalent N(1), two equivalent N(2), and two equivalent N(3) atoms. Mn(1) is bonded in a tetrahedral geometry to one N(1), one N(2), one N(3), and one N(4) atom. There are four 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), and one Mn(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), and one Mn(1) atom. In the third N site, N(3) is bonded in a distorted single-bond geometry to one K(1), two equivalent K(2), and one Mn(1) atom. In the fourth N site, N(4) is bonded in a distorted single-bond geometry to one K(2), three equivalent K(1), and one Mn(1) atom. is represented by the CIF file [CIF]
