Abstract

In the first K1+ site, K1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of K–O bond distances ranging from 2.69–3.29 Å. In the second K1+ site, K1+ is bonded to six O2- atoms to form distorted KO6 octahedra that share corners with six MoO4 tetrahedra and an edgeedge with one KO6 octahedra. There are a spread of K–O bond distances ranging from 2.72–3.04 Å. There are four 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 KO6 octahedra. The corner-sharing octahedra tilt angles range from 51–57°.

In the sixth O2- site, O2- is bonded in a distorted trigonal planar geometry to one K1+, one Mo6+, and one Cu2+ atom. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to one Mo6+ and two Cu2+ atoms. In the eighth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one K1+, one Mo6+, and one Cu2+ atom. In the ninth O2- site, O2- is bonded in a 3-coordinate geometry to one K1+, one Mo6+, and one Cu2+ atom. In the tenth O2- site, O2- is bonded in a 2-coordinate geometry to one Mo6+ and two Cu2+ atoms. In the eleventh O2- site, O2- is bonded in a distorted trigonal planar geometry to one K1+, one Mo6+, and one Cu2+ atom. In the twelfth O2- site, O2- is bonded in a 1-coordinate geometry to one K1+ and one Mo6+ atom. In the thirteenth O2- site, O2- is bonded in a trigonal planar geometry to one Mo6+ and two Cu2+ atoms. In the fourteenth O2- site, O2- is bonded in a bent 150 degrees geometry to one Mo6+ and one Cu2+ atom. In the fifteenth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Mo6+ and two Cu2+ atoms. In the sixteenth O2- site, O2- is bonded in a distorted single-bond geometry to two K1+, one Mo6+, and one Cu2+ atom.« less
