Abstract

Nb4IrSe10 is trigonal omega-derived structured and crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of one Nb4IrSe10 sheet oriented in the (0, -1, 1) direction. there are two inequivalent Nb+4.25+ sites. In the first Nb+4.25+ site, Nb+4.25+ is bonded to six Se2- atoms to form NbSe6 octahedra that share an edgeedge with one IrSe6 octahedra and edges with five NbSe6 octahedra. There are a spread of Nb–Se bond distances ranging from 2.55–2.75 Å. In the second Nb+4.25+ site, Nb+4.25+ is bonded to six Se2- atoms to form NbSe6 octahedra that share edges with two equivalent IrSe6 octahedra and edges with four NbSe6 octahedra. There are a spread of Nb–Se bond distances ranging from 2.50–2.79 Å. Ir3+ is bonded to six Se2- atoms to form IrSe6 octahedra that share edges with six NbSe6 octahedra. There are two shorter (2.55 Å) and four longer (2.56 Å) Ir–Se bond lengths. There are five inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a 3-coordinate geometry to two Nb+4.25+ and one Ir3+ atom. In the second Se2- site, Se2- is bonded in a 3-coordinate geometry to two equivalent Nb+4.25+ and one Ir3+ atom. In the thirdmore »« less
