The compound described by URh2B2C crystallizes in the tetragonal I4/mmm space group. U(1) is bonded in a distorted square co-planar geometry to four equivalent C(1) atoms. Rh(1) is bonded to four equivalent B(1) atoms to form a mixture of distorted edge and corner-sharing RhB4 tetrahedra. B(1) is bonded in a distorted single-bond geometry to four equivalent Rh(1) and one C(1) atom. C(1) is bonded in a distorted linear geometry to four equivalent U(1) and two equivalent B(1) atoms. is represented by the CIF file [CIF]
