U2PtC2 crystallizes in the tetragonal I4/mmm space group. U(1) is bonded to five equivalent C(1) atoms to form a mixture of distorted edge and corner-sharing UC5 square pyramids. Pt(1) is bonded in a linear geometry to two equivalent C(1) atoms. C(1) is bonded to five equivalent U(1) and one Pt(1) atom to form a mixture of edge and corner-sharing CU5Pt octahedra. The corner-sharing octahedral tilt angles range from 0-10°.
U2PtC2 crystallizes in the tetragonal I4/mmm space group. U(1) is bonded to five equivalent C(1) atoms to form a mixture of distorted edge and corner-sharing UC5 square pyramids. There is one shorter (2.31 Å) and four longer (2.52 Å) U(1)-C(1) bond lengths. Pt(1) is bonded in a linear geometry to two equivalent C(1) atoms. Both Pt(1)-C(1) bond lengths are 2.11 Å. C(1) is bonded to five equivalent U(1) and one Pt(1) atom to form a mixture of edge and corner-sharing CU5Pt octahedra. The corner-sharing octahedral tilt angles range from 0-10°.
