The material structure described by La2YC6 crystallizes in the monoclinic C2/m space group. La(1) is bonded in a distorted q4 geometry to two equivalent C(1), three equivalent C(3), and five equivalent C(2) atoms. Y(1) is bonded in a 10-coordinate geometry to four equivalent C(3) and six equivalent C(1) atoms. There are three inequivalent C sites. In the first C site, C(1) is bonded in a distorted linear geometry to two equivalent La(1), three equivalent Y(1), and one C(3) atom. In the second C site, C(2) is bonded in a 6-coordinate geometry to five equivalent La(1) and one C(2) atom. In the third C site, C(3) is bonded in a 6-coordinate geometry to three equivalent La(1), two equivalent Y(1), and one C(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
