TbNb(6)Sn(6): the first ternary compound from the rare earth–niobium–tin system

The title compound, terbium hexa­niobium hexastannide, TbNb(6)Sn(6), is the first ternary compound from the rare earth–niobium–tin system. It has the HfFe(6)Ge(6) structure type, which can be analysed as an inter­growth of the Zr(4)Al(3) and CaCu(5) structures. All the atoms lie on special positions...

description The title compound, terbium hexa­niobium hexastannide, TbNb(6)Sn(6), is the first ternary compound from the rare earth–niobium–tin system. It has the HfFe(6)Ge(6) structure type, which can be analysed as an inter­growth of the Zr(4)Al(3) and CaCu(5) structures. All the atoms lie on special positions; their coordination geometries and site symmetries are: Tb (dodeca­hedron) 6/mmm; Nb (distorted icosa­hedron) 2mm; Sn (Frank–Caspar polyhedron, CN = 14–15) 6mm and [Image: see text] m2; Sn (distorted icosa­hedron) [Image: see text] m2. The structure contains a graphite-type Sn network, Kagome nets of Nb atoms, and Tb atoms alternating with Sn2 dumbbells in the channels.
