Materials Data on U by Materials Project
U is beta Uranium structured and crystallizes in the tetragonal P4_2nm space group. The structure is three-dimensional. there are eight inequivalent U sites. In the first U site, U is bonded to twelve U atoms to form distorted edge-sharing UU12 cuboctahedra. There are a spread of U–U bond distances ranging from 2.89–3.46 Å. In the second U site, U is bonded in a 2-coordinate geometry to eleven U atoms. There are a spread of U–U bond distances ranging from 2.70–3.45 Å. In the third U site, U is bonded in a 1-coordinate geometry to eleven U atoms. There are a spread of U–U bond distances ranging from 2.56–3.36 Å. In the fourth U site, U is bonded in a 1-coordinate geometry to fourteen U atoms. There are a spread of U–U bond distances ranging from 2.98–3.37 Å. In the fifth U site, U is bonded in a 12-coordinate geometry to twelve U atoms. There are a spread of U–U bond distances ranging from 2.68–3.32 Å. In the sixth U site, U is bonded in a 3-coordinate geometry to fourteen U atoms. There are one shorter (3.12 Å) and four longer (3.61 Å) U–U bond lengths. In the seventh U site, U is bonded in a 3-coordinate geometry to fourteen U atoms. There are a spread of U–U bond distances ranging from 2.68–3.32 Å. In the eighth U site, U is bonded in a 3-coordinate geometry to fourteen U atoms. There are a spread of U–U bond distances ranging from 2.68–3.61 Å.
