Abstract

KNa3WO5 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. K1+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of K–O bond distances ranging from 2.89–3.01 Å. There are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to five O2- atoms to form distorted NaO5 trigonal bipyramids that share a cornercorner with one WO5 trigonal bipyramid, corners with five NaO5 trigonal bipyramids, edges with two equivalent WO5 trigonal bipyramids, and edges with four NaO5 trigonal bipyramids. There are a spread of Na–O bond distances ranging from 2.30–2.40 Å. In the second Na1+ site, Na1+ is bonded to five O2- atoms to form NaO5 trigonal bipyramids that share corners with two equivalent NaO5 trigonal bipyramids, corners with five equivalent WO5 trigonal bipyramids, and edges with four equivalent NaO5 trigonal bipyramids. There are a spread of Na–O bond distances ranging from 2.32–2.69 Å. W6+ is bonded to five O2- atoms to form WO5 trigonal bipyramids that share corners with seven NaO5 trigonal bipyramids and edges with four equivalent NaO5 trigonal bipyramids. There are a spread of W–O bond distances ranging from 1.86–1.94 Å. There are four inequivalent O2- sites.more »« less
