Materials Data on Ni6S5 by Materials Project
Abstract
Ni6S5 crystallizes in the orthorhombic Cmc2_1 space group. The structure is three-dimensional. there are six inequivalent Ni+1.67+ sites. In the first Ni+1.67+ site, Ni+1.67+ is bonded to five S2- atoms to form distorted NiS5 trigonal bipyramids that share corners with two equivalent NiS5 square pyramids, corners with five NiS4 tetrahedra, corners with six NiS5 trigonal bipyramids, and edges with four NiS5 trigonal bipyramids. There are one shorter (2.29 Å) and four longer (2.35 Å) Ni–S bond lengths. In the second Ni+1.67+ site, Ni+1.67+ is bonded to five S2- atoms to form distorted NiS5 trigonal bipyramids that share corners with five NiS4 tetrahedra, corners with six NiS5 trigonal bipyramids, edges with two equivalent NiS5 square pyramids, and edges with four NiS5 trigonal bipyramids. There are a spread of Ni–S bond distances ranging from 2.24–2.39 Å. In the third Ni+1.67+ site, Ni+1.67+ is bonded to five S2- atoms to form distorted NiS5 trigonal bipyramids that share corners with two equivalent NiS5 square pyramids, corners with four NiS4 tetrahedra, corners with eight NiS5 trigonal bipyramids, and edges with four NiS5 trigonal bipyramids. There are three shorter (2.31 Å) and two longer (2.33 Å) Ni–S bond lengths. In the fourth Ni+1.67+ site, Ni+1.67+ ismore »
