description: K2Mo6H2OCl14 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded to six Cl1- atoms to form distorted KCl6 pentagonal pyramids that share corners with two equivalent MoCl5 square pyramids, corners with two equivalent MoCl5 trigonal bipyramids, and edges with two equivalent KCl6 pentagonal pyramids. There are a spread of K–Cl bond distances ranging from 3.19–3.38 Å. In the second K1+ site, K1+ is bonded in a 5-coordinate geometry to one O2- and four Cl1- atoms. The K–O bond length is 2.79 Å. There are a spread of K–Cl bond distances ranging from 3.16–3.49 Å. There are six inequivalent Mo2+ sites. In the first Mo2+ site, Mo2+ is bonded in a distorted T-shaped geometry to three Cl1- atoms. There are a spread of Mo–Cl bond distances ranging from 2.46–2.57 Å. In the second Mo2+ site, Mo2+ is bonded to five Cl1- atoms to form edge-sharing MoCl5 trigonal bipyramids. There are a spread of Mo–Cl bond distances ranging from 2.43–2.60 Å. In the third Mo2+ site, Mo2+ is bonded to five Cl1- atoms to form MoCl5 square pyramids that share corners with two equivalent KCl6 pentagonal pyramids and an edgeedge with one MoCl5 trigonal bipyramid.
