Materials Data on U2Mn(PO11)2 by Materials Project
(UPO6)2MnO10 crystallizes in the monoclinic C2/m space group. The structure is two-dimensional and consists of two MnO10 clusters and two UPO6 sheets oriented in the (0, 1, 0) direction. In each MnO10 cluster, Mn is bonded in a distorted octahedral geometry to six O atoms. There is two shorter (1.66 Å) and four longer (2.26 Å) Mn–O bond length. There are three inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one Mn atom. In the second O site, O is bonded in a single-bond geometry to one O atom. The O–O bond length is 1.24 Å. In the third O site, O is bonded in a bent 120 degrees geometry to one Mn and one O atom. In each UPO6 sheet, U is bonded to six O atoms to form UO6 octahedra that share corners with four equivalent PO4 tetrahedra. There are two shorter (1.81 Å) and four longer (2.28 Å) U–O bond lengths. P is bonded to four O atoms to form PO4 tetrahedra that share corners with four equivalent UO6 octahedra. The corner-sharing octahedral tilt angles are 36°. All P–O bond lengths are 1.55 Å. There are four inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one U atom. In the second O site, O is bonded in a single-bond geometry to one U atom. In the third O site, O is bonded in a bent 150 degrees geometry to one U and one P atom. In the fourth O site, O is bonded in a bent 150 degrees geometry to one U and one P atom.
