La(C2N3)3 crystallizes in the orthorhombic Cmcm space group. La(1) is bonded in a 9-coordinate geometry to one N(2), two equivalent N(3), two equivalent N(4), and four 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(2) and one N(3) atom. In the second C site, C(2) is bonded in a linear geometry to one N(1) and one N(4) atom. There are four inequivalent N sites. In the first N site, N(3) is bonded in a distorted bent 150 degrees geometry to one La(1) and one C(1) atom. In the second N site, N(4) is bonded in a bent 120 degrees geometry to one La(1) and two equivalent C(2) atoms. In the third N site, N(1) is bonded in a bent 150 degrees geometry to one La(1) and one C(2) atom. In the fourth N site, N(2) is bonded in a distorted bent 120 degrees geometry to one La(1) and two equivalent C(1) atoms.
