Materials Data on U2Ge4Mo3 by Materials Project

Abstract

U2Mo3Ge4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. U is bonded in a 7-coordinate geometry to two equivalent Mo and seven Ge atoms. There are one shorter (3.14 Å) and one longer (3.27 Å) U–Mo bond lengths. There are a spread of U–Ge bond distances ranging from 2.86–3.01 Å. There are two inequivalent Mo sites. In the first Mo site, Mo is bonded to six Ge atoms to form distorted corner-sharing MoGe6 octahedra. The corner-sharing octahedral tilt angles are 47°. All Mo–Ge bond lengths are 2.69 Å. In the second Mo site, Mo is bonded in a 6-coordinate geometry to two equivalent U and six Ge atoms. There are a spread of Mo–Ge bond distances ranging from 2.55–2.69 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to four equivalent U, four Mo, and one Ge atom. The Ge–Ge bond length is 2.76 Å. In the second Ge site, Ge is bonded in a 9-coordinate geometry to three equivalent U, five Mo, and one Ge atom. The Ge–Ge bond length is 2.78 Å.
