The material structure described by La4YC10 crystallizes in the orthorhombic Fmmm space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a distorted q4 geometry to two equivalent C(2), two equivalent C(3), and six equivalent C(1) atoms. In the second La site, La(2) is bonded in a distorted q4 geometry to two equivalent C(1) and eight equivalent C(2) atoms. Y(1) is bonded in a distorted q4 geometry to four equivalent C(1) and six equivalent C(3) atoms. There are three inequivalent C sites. In the first C site, C(1) is bonded in a 6-coordinate geometry to one La(2), three equivalent La(1), one Y(1), and one C(1) atom. In the second C site, C(2) is bonded in a 6-coordinate geometry to one La(1), four equivalent La(2), and one C(2) atom. In the third C site, C(3) is bonded in a 6-coordinate geometry to two equivalent La(1), three equivalent Y(1), and one C(3) atom. is represented by the CIF card [CIF]
