Abstract

Tb is alpha La-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are five inequivalent Tb sites. In the first Tb site, Tb is bonded to twelve Tb atoms to form a mixture of edge, face, and corner-sharing TbTb12 cuboctahedra. There are a spread of Tb–Tb bond distances ranging from 3.55–3.58 Å. In the second Tb site, Tb is bonded to twelve Tb atoms to form a mixture of edge, face, and corner-sharing TbTb12 cuboctahedra. There are six shorter (3.56 Å) and six longer (3.58 Å) Tb–Tb bond lengths. In the third Tb site, Tb is bonded to twelve Tb atoms to form a mixture of edge, face, and corner-sharing TbTb12 cuboctahedra. There are a spread of Tb–Tb bond distances ranging from 3.55–3.58 Å. In the fourth Tb site, Tb is bonded to twelve Tb atoms to form a mixture of edge, face, and corner-sharing TbTb12 cuboctahedra. All Tb–Tb bond lengths are 3.58 Å. In the fifth Tb site, Tb is bonded to twelve Tb atoms to form a mixture of edge, face, and corner-sharing TbTb12 cuboctahedra. All Tb–Tb bond lengths are 3.58 Å.
