The structure described by UNi(OF2)3 crystallizes in the monoclinic C2/c space group. U(1) is bonded in a 9-coordinate geometry to one O(2), two equivalent F(1), two equivalent F(2), and four equivalent F(3) atoms. Ni(1) is bonded in an octahedral geometry to two equivalent O(1), two equivalent F(1), and two equivalent F(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one Ni(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one U(1) atom. There are three inequivalent F sites. In the first F site, F(1) is bonded in a distorted bent 150 degrees geometry to one U(1) and one Ni(1) atom. In the second F site, F(2) is bonded in a distorted bent 120 degrees geometry to one U(1) and one Ni(1) atom. In the third F site, F(3) is bonded in a distorted bent 120 degrees geometry to two equivalent U(1) atoms. is represented by the CIF card [CIF]
