Materials Data on UMn5Al7 by Materials Project
Abstract
UMn5Al7 crystallizes in the orthorhombic Imm2 space group. The structure is three-dimensional. U is bonded in a 12-coordinate geometry to ten Mn and ten Al atoms. There are a spread of U–Mn bond distances ranging from 3.10–3.44 Å. There are a spread of U–Al bond distances ranging from 2.93–3.21 Å. There are two inequivalent Mn sites. In the first Mn site, Mn is bonded in a 12-coordinate geometry to two equivalent U, three Mn, and seven Al atoms. There are a spread of Mn–Mn bond distances ranging from 2.34–2.62 Å. There are a spread of Mn–Al bond distances ranging from 2.50–2.67 Å. In the second Mn site, Mn is bonded in a distorted q6 geometry to two equivalent U, four equivalent Mn, and six Al atoms. There are a spread of Mn–Al bond distances ranging from 2.66–2.70 Å. There are five inequivalent Al sites. In the first Al site, Al is bonded in a 10-coordinate geometry to one U, four equivalent Mn, and five Al atoms. There are a spread of Al–Al bond distances ranging from 2.67–2.88 Å. In the second Al site, Al is bonded in a 10-coordinate geometry to one U, six Mn, and seven Al atoms. Theremore »
