Abstract

Ti2W3As4 crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are two inequivalent Ti3+ sites. In the first Ti3+ site, Ti3+ is bonded in a rectangular see-saw-like geometry to four As3- atoms. There are a spread of Ti–As bond distances ranging from 2.76–2.81 Å. In the second Ti3+ site, Ti3+ is bonded to five As3- atoms to form distorted TiAs5 trigonal bipyramids that share corners with eight WAs5 trigonal bipyramids, edges with two equivalent WAs5 square pyramids, edges with two equivalent TiAs5 trigonal bipyramids, and edges with two WAs5 trigonal bipyramids. There are a spread of Ti–As bond distances ranging from 2.50–2.60 Å. There are three inequivalent W2+ sites. In the first W2+ site, W2+ is bonded to five As3- atoms to form WAs5 square pyramids that share corners with eight WAs5 trigonal bipyramids, edges with two equivalent WAs5 square pyramids, edges with two equivalent TiAs5 trigonal bipyramids, and edges with two WAs5 trigonal bipyramids. There are a spread of W–As bond distances ranging from 2.59–2.64 Å.
