Materials Data on KDy(MoO4)2 by Materials Project

KDy(MoO4)2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. K1+ is bonded in a 12-coordinate geometry to twelve O2- atoms. There are a spread of K–O bond distances ranging from 2.79–3.38 Å. Dy3+ is bonded in a 6-coordinate geometry to eight O2- atoms. There are a spread of Dy–O bond distances ranging from 2.29–2.70 Å. Mo6+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mo–O bond distances ranging from 1.79–2.43 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent K1+ and two equivalent Mo6+ atoms. In the second O2- site, O2- is bonded in a 1-coordinate geometry to one K1+, two equivalent Dy3+, and one Mo6+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one K1+, one Dy3+, and two equivalent Mo6+ atoms. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent K1+, one Dy3+, and one Mo6+ atom.
