Abstract

Tb2CuZnSi2 is hexagonal omega structure-derived structured and crystallizes in the orthorhombic Pmm2 space group. The structure is three-dimensional. there are two inequivalent Tb sites. In the first Tb site, Tb is bonded to two equivalent Cu, four equivalent Zn, and six Si atoms to form a mixture of face and edge-sharing TbZn4Cu2Si6 cuboctahedra. Both Tb–Cu bond lengths are 3.08 Å. All Tb–Zn bond lengths are 3.11 Å. There are four shorter (3.11 Å) and two longer (3.16 Å) Tb–Si bond lengths. In the second Tb site, Tb is bonded to four equivalent Cu, two equivalent Zn, and six Si atoms to form a mixture of face and edge-sharing TbZn2Cu4Si6 cuboctahedra. All Tb–Cu bond lengths are 3.10 Å. Both Tb–Zn bond lengths are 3.13 Å. There are two shorter (3.06 Å) and four longer (3.10 Å) Tb–Si bond lengths. Cu is bonded in a 9-coordinate geometry to six Tb and three Si atoms. There are one shorter (2.32 Å) and two longer (2.33 Å) Cu–Si bond lengths. Zn is bonded in a distorted trigonal planar geometry to six Tb and three Si atoms. All Zn–Si bond lengths are 2.39 Å. There are two inequivalent Si sites. In the first Si site,more »« less
