The crystal structure described by LiLa(CN2)2 crystallizes in the monoclinic P2_1/m space group. Li(1) is bonded to one N(1), one N(4), and two equivalent N(3) atoms to form distorted corner-sharing LiN4 tetrahedra. La(1) is bonded in a 8-coordinate geometry to one N(3), two equivalent N(1), two equivalent N(4), and three equivalent N(2) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a linear geometry to one N(1) and one N(2) atom. In the second C site, C(2) is bonded in a linear geometry to one N(3) and one N(4) atom. There are four inequivalent N sites. In the first N site, N(1) is bonded to one Li(1), two equivalent La(1), and one C(1) atom to form a mixture of distorted edge and corner-sharing NLiLa2C trigonal pyramids. In the second N site, N(2) is bonded in a distorted single-bond geometry to three equivalent La(1) and one C(1) atom. In the third N site, N(3) is bonded in a 4-coordinate geometry to two equivalent Li(1), one La(1), and one C(2) atom. In the fourth N site, N(4) is bonded to one Li(1), two equivalent La(1), and one C(2) atom to form a mixture of distorted edge and corner-sharing NLiLa2C tetrahedra. is represented by the CIF file [CIF]
