The crystal structure described by KSm2N7 crystallizes in the orthorhombic Pnnm space group. K(1) is bonded in a 4-coordinate geometry to two equivalent N(3) and two equivalent N(4) atoms. Sm(1) is bonded in a 6-coordinate geometry to one N(1), one N(4), two equivalent N(2), and two equivalent N(3) atoms. There are four inequivalent N sites. In the first N site, N(4) is bonded in a 3-coordinate geometry to one K(1), one Sm(1), and one N(2) atom. In the second N site, N(1) is bonded in a bent 150 degrees geometry to two equivalent Sm(1) atoms. In the third N site, N(2) is bonded in a 3-coordinate geometry to two equivalent Sm(1) and one N(4) atom. In the fourth N site, N(3) is bonded in a trigonal planar geometry to one K(1) and two equivalent Sm(1) atoms. is represented by the CIF card [CIF]
