Materials Data on Nb2CrMo2 by Materials Project

Abstract

NbMoNbCrMo crystallizes in the orthorhombic Fmm2 space group. The structure is one-dimensional and consists of four NbCrMo ribbons oriented in the (1, 0, 0) direction and four NbMo ribbons oriented in the (1, 0, 0) direction. In each NbCrMo ribbon, Nb is bonded in a 8-coordinate geometry to two equivalent Cr atoms. Both Nb–Cr bond lengths are 2.66 Å. Mo is bonded in a 2-coordinate geometry to two equivalent Cr atoms. Both Mo–Cr bond lengths are 2.56 Å. Cr is bonded in a 2-coordinate geometry to two equivalent Nb and two equivalent Mo atoms. In each NbMo ribbon, Nb is bonded in a 10-coordinate geometry to two equivalent Mo atoms. Both Nb–Mo bond lengths are 2.82 Å. Mo is bonded in a 8-coordinate geometry to two equivalent Nb atoms.
