Abstract

Tb4C2Br3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are four inequivalent Tb sites. In the first Tb site, Tb is bonded to two equivalent C and four Br atoms to form distorted TbC2Br4 octahedra that share corners with four TbC4Br2 octahedra and edges with ten TbC2Br4 octahedra. The corner-sharing octahedral tilt angles are 4°. Both Tb–C bond lengths are 2.43 Å. There are a spread of Tb–Br bond distances ranging from 2.78–3.19 Å. In the second Tb site, Tb is bonded to four C and two equivalent Br atoms to form a mixture of edge and corner-sharing TbC4Br2 octahedra. The corner-sharing octahedra tilt angles range from 0–4°. There are a spread of Tb–C bond distances ranging from 2.60–2.71 Å. Both Tb–Br bond lengths are 2.96 Å. In the third Tb site, Tb is bonded to three C and three Br atoms to form a mixture of distorted edge and corner-sharing TbC3Br3 octahedra. The corner-sharing octahedra tilt angles range from 1–21°. There are two shorter (2.51 Å) and one longer (2.55 Å) Tb–C bond lengths. There are one shorter (2.93 Å) and two longer (3.00 Å) Tb–Br bond lengths. In the fourth Tb site, Tb ismore »« less
