UCrC2 crystallizes in the orthorhombic Pnma space group. U(1) is bonded in a 6-coordinate geometry to three equivalent C(1) and three equivalent C(2) atoms. Cr(1) is bonded in a 6-coordinate geometry to three equivalent C(1) and three equivalent C(2) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded to three equivalent U(1), three equivalent Cr(1), and one C(2) atom to form distorted edge-sharing CU3Cr3C hexagonal pyramids. In the second C site, C(2) is bonded in a 7-coordinate geometry to three equivalent U(1), three equivalent Cr(1), and one C(1) atom.
UCrC2 crystallizes in the orthorhombic Pnma space group. U(1) is bonded in a 6-coordinate geometry to three equivalent C(1) and three equivalent C(2) atoms. There is one shorter (2.37 Å) and two longer (2.50 Å) U(1)-C(1) bond lengths. There are a spread of U(1)-C(2) bond distances ranging from 2.41-2.65 Å. Cr(1) is bonded in a 6-coordinate geometry to three equivalent C(1) and three equivalent C(2) atoms. There is one shorter (1.99 Å) and two longer (2.16 Å) Cr(1)-C(1) bond lengths. There are two shorter (1.95 Å) and one longer (2.28 Å) Cr(1)-C(2) bond length. There are two inequivalent C sites. In the first C site, C(1) is bonded to three equivalent U(1), three equivalent Cr(1), and one C(2) atom to form distorted edge-sharing CU3Cr3C hexagonal pyramids. The C(1)-C(2) bond length is 1.53 Å. In the second C site, C(2) is bonded in a 7-coordinate geometry to three equivalent U(1), three equivalent Cr(1), and one C(1) atom.
