The crystal structure described by Tm2(CN2)3 crystallizes in the monoclinic C2/m space group. Tm(1) is bonded in a 7-coordinate geometry to two equivalent N(1), two equivalent N(3), 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(2) and one N(3) atom. In the second C site, C(2) is bonded in a linear geometry to two equivalent N(1) atoms. There are three inequivalent N sites. In the first N site, N(1) is bonded in a 3-coordinate geometry to two equivalent Tm(1) and one C(2) atom. In the second N site, N(2) is bonded to three equivalent Tm(1) and one C(1) atom to form a mixture of distorted corner and edge-sharing NTm3C tetrahedra. In the third N site, N(3) is bonded in a distorted trigonal planar geometry to two equivalent Tm(1) and one C(1) atom. is represented by the CIF card [CIF]
