Ce2(CN2)3 crystallizes in the monoclinic C2/m space group. Ce(1) is bonded in a 7-coordinate geometry to two equivalent N(2), two equivalent N(3), and three equivalent N(1) 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 two equivalent N(3) atoms. There are three inequivalent N sites. In the first N site, N(1) is bonded to three equivalent Ce(1) and one C(1) atom to form a mixture of distorted corner and edge-sharing NCe3C tetrahedra. In the second N site, N(2) is bonded in a distorted trigonal planar geometry to two equivalent Ce(1) and one C(1) atom. In the third N site, N(3) is bonded in a distorted trigonal planar geometry to two equivalent Ce(1) and one C(2) atom.
Ce2(CN2)3 crystallizes in the monoclinic C2/m space group. Ce(1) is bonded in a 7-coordinate geometry to two equivalent N(2), two equivalent N(3), and three equivalent N(1) atoms. Both Ce(1)-N(2) bond lengths are 2.54 Å. There is one shorter (2.47 Å) and one longer (2.53 Å) Ce(1)-N(3) bond length. There are two shorter (2.58 Å) and one longer (2.61 Å) Ce(1)-N(1) bond length. 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. The C(1)-N(1) bond length is 1.24 Å. The C(1)-N(2) bond length is 1.21 Å. In the second C site, C(2) is bonded in a linear geometry to two equivalent N(3) atoms. Both C(2)-N(3) bond lengths are 1.23 Å. There are three inequivalent N sites.
