Abstract

MgCu2(MoO4)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Mg2+ is bonded to six O2- atoms to form MgO6 octahedra that share corners with six MoO4 tetrahedra, an edgeedge with one MgO6 octahedra, and edges with two equivalent CuO5 trigonal bipyramids. There are a spread of Mg–O bond distances ranging from 2.10–2.29 Å. There are two inequivalent Mo6+ sites. In the first Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with three equivalent MgO6 octahedra and corners with two equivalent CuO5 trigonal bipyramids. The corner-sharing octahedra tilt angles range from 29–49°. There are a spread of Mo–O bond distances ranging from 1.79–1.84 Å. In the second Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with three equivalent MgO6 octahedra and corners with three equivalent CuO5 trigonal bipyramids. The corner-sharing octahedra tilt angles range from 50–60°. There are a spread of Mo–O bond distances ranging from 1.77–1.88 Å. There are two inequivalent Cu1+ sites. In the first Cu1+ site, Cu1+ is bonded to five O2- atoms to form CuO5 trigonal bipyramids that share corners with five MoO4 tetrahedra and edges with twomore »« less
