Materials Data on U2(Ni7B2)3 by Materials Project
U2Ni21B6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. U is bonded in a distorted tetrahedral geometry to four equivalent Ni atoms. All U–Ni bond lengths are 2.49 Å. There are three inequivalent Ni sites. In the first Ni site, Ni is bonded in a distorted bent 150 degrees geometry to one Ni and two equivalent B atoms. The Ni–Ni bond length is 2.56 Å. Both Ni–B bond lengths are 2.07 Å. In the second Ni site, Ni is bonded to one U and three equivalent B atoms to form a mixture of distorted corner and edge-sharing NiUB3 tetrahedra. All Ni–B bond lengths are 2.14 Å. In the third Ni site, Ni is bonded in a cuboctahedral geometry to twelve equivalent Ni atoms. B is bonded in a 8-coordinate geometry to eight Ni atoms.
