Abstract
W2CuZnO7 crystallizes in the monoclinic P2/c space group. The structure is three-dimensional. there are three inequivalent W+5.50+ sites. In the first W+5.50+ site, W+5.50+ is bonded to four O2- atoms to form WO4 tetrahedra that share a cornercorner with one ZnO6 octahedra, a cornercorner with one WO4 tetrahedra, and corners with two equivalent ZnO5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 48°. There are a spread of W–O bond distances ranging from 1.79–1.92 Å. In the second W+5.50+ site, W+5.50+ is bonded to four O2- atoms to form WO4 tetrahedra that share a cornercorner with one WO4 tetrahedra and corners with three equivalent ZnO5 trigonal bipyramids. There are a spread of W–O bond distances ranging from 1.82–1.93 Å. In the third W+5.50+ site, W+5.50+ is bonded to four O2- atoms to form WO4 tetrahedra that share corners with two equivalent ZnO6 octahedra and a cornercorner with one WO4 tetrahedra. The corner-sharing octahedra tilt angles range from 28–47°. There are a spread of W–O bond distances ranging from 1.82–1.94 Å. There are two inequivalent Cu1+ sites. In the first Cu1+ site, Cu1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Cu–O bond distancesmore »

In the second Cu1+ site, Cu1+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There is two shorter (1.92 Å) and two longer (2.04 Å) Cu–O bond length.
