Materials Data on Zr3(UGe2)2 by Materials Project

U2Zr3Ge4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. U is bonded in a 7-coordinate geometry to seven Ge atoms. There are a spread of U–Ge bond distances ranging from 2.91–3.22 Å. There are two inequivalent Zr sites. In the first Zr site, Zr is bonded in a 6-coordinate geometry to six Ge atoms. There are a spread of Zr–Ge bond distances ranging from 2.72–2.87 Å. In the second Zr site, Zr is bonded to six Ge atoms to form corner-sharing ZrGe6 octahedra. The corner-sharing octahedral tilt angles are 50°. There are a spread of Zr–Ge bond distances ranging from 2.84–2.92 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 Zr, and one Ge atom. The Ge–Ge bond length is 2.82 Å. In the second Ge site, Ge is bonded in a 9-coordinate geometry to three equivalent U, five Zr, and one Ge atom. The Ge–Ge bond length is 2.77 Å.
