Materials Data on U3Si2C3 by Materials Project
(UC1)2USi2C crystallizes in the orthorhombic Immm space group. The structure is two-dimensional and consists of two UC1 sheets oriented in the (0, 0, 1) direction and two USi2C sheets oriented in the (0, 0, 1) direction. In each UC1 sheet, U4+ is bonded in a 4-coordinate geometry to four equivalent C4- atoms. All U–C bond lengths are 2.23 Å. C4- is bonded to four equivalent U4+ atoms to form a mixture of edge and corner-sharing CU4 tetrahedra. In each USi2C sheet, U4+ is bonded in a square co-planar geometry to four equivalent C4- atoms. All U–C bond lengths are 2.60 Å. Si is bonded in a single-bond geometry to one C4- atom. The Si–C bond length is 1.83 Å. C4- is bonded to four equivalent U4+ and two equivalent Si atoms to form a mixture of edge and corner-sharing CU4Si2 octahedra. The corner-sharing octahedral tilt angles are 0°.
