Materials Data on UB2C by Materials Project

UB2C crystallizes in the orthorhombic Pmma space group. The structure is two-dimensional and consists of one UB2C sheet oriented in the (0, 1, 0) direction. U4+ is bonded in a distorted rectangular see-saw-like geometry to four equivalent C4- atoms. All U–C bond lengths are 2.45 Å. B is bonded in a distorted single-bond geometry to one C4- atom. The B–C bond length is 1.52 Å. C4- is bonded to four equivalent U4+ and two equivalent B atoms to form a mixture of distorted edge and corner-sharing CU4B2 octahedra. The corner-sharing octahedral tilt angles are 39°.
