Materials Data on NbTe4Ir by Materials Project
Abstract
NbIrTe4 crystallizes in the orthorhombic Pmn2_1 space group. The structure is two-dimensional and consists of two NbIrTe4 sheets oriented in the (0, 0, 1) direction. there are two inequivalent Nb5+ sites. In the first Nb5+ site, Nb5+ is bonded to six Te2- atoms to form distorted NbTe6 octahedra that share edges with two equivalent IrTe6 octahedra and edges with four NbTe6 octahedra. There are a spread of Nb–Te bond distances ranging from 2.67–2.94 Å. In the second Nb5+ site, Nb5+ is bonded to six Te2- atoms to form distorted NbTe6 octahedra that share edges with two equivalent IrTe6 octahedra and edges with four NbTe6 octahedra. There are a spread of Nb–Te bond distances ranging from 2.67–2.92 Å. There are two inequivalent Ir3+ sites. In the first Ir3+ site, Ir3+ is bonded to six Te2- atoms to form IrTe6 octahedra that share edges with two equivalent NbTe6 octahedra and edges with four IrTe6 octahedra. There are a spread of Ir–Te bond distances ranging from 2.67–2.73 Å. In the second Ir3+ site, Ir3+ is bonded to six Te2- atoms to form IrTe6 octahedra that share edges with two equivalent NbTe6 octahedra and edges with four IrTe6 octahedra. There are a spread ofmore »
