The compound described by EuCN2 crystallizes in the orthorhombic Pnma space group. Eu(1) is bonded to three equivalent N(1) and three equivalent N(2) atoms to form a mixture of distorted edge and corner-sharing EuN6 octahedra. The corner-sharing octahedral tilt angles are 65°. C(1) is bonded in a linear geometry to one N(1) and one N(2) atom. There are two inequivalent N sites. In the first N site, N(1) is bonded to three equivalent Eu(1) and one C(1) atom to form a mixture of distorted edge and corner-sharing NEu3C tetrahedra. In the second N site, N(2) is bonded to three equivalent Eu(1) and one C(1) atom to form a mixture of distorted edge and corner-sharing NEu3C tetrahedra. is represented by the CIF file [CIF]
