KLa2N7 crystallizes in the orthorhombic Pnnm space group. K(1) is bonded in a 6-coordinate geometry to two equivalent N(2), two equivalent N(3), and two equivalent N(4) atoms. La(1) is bonded in a 6-coordinate geometry to two equivalent N(2), two equivalent N(3), and two equivalent N(4) atoms. There are four inequivalent N sites. In the first N site, N(4) is bonded to one K(1), two equivalent La(1), and one N(1) atom to form distorted corner-sharing NKLa2N trigonal pyramids. In the second N site, N(1) is bonded in a distorted bent 120 degrees geometry to two equivalent N(4) atoms. In the third N site, N(2) is bonded in a 4-coordinate geometry to one K(1), two equivalent La(1), and one N(3) atom. In the fourth N site, N(3) is bonded in a 4-coordinate geometry to one K(1), two equivalent La(1), and one N(2) atom.
