Abstract

Mo15Se19 crystallizes in the monoclinic C2/c space group. The structure is two-dimensional and consists of two Mo15Se19 sheets oriented in the (1, 0, 0) direction. there are eight inequivalent Mo+2.53+ sites. In the first Mo+2.53+ site, Mo+2.53+ is bonded in a distorted trigonal non-coplanar geometry to three Se2- atoms. There are a spread of Mo–Se bond distances ranging from 2.57–2.60 Å. In the second Mo+2.53+ site, Mo+2.53+ is bonded in a distorted see-saw-like geometry to four Se2- atoms. There are a spread of Mo–Se bond distances ranging from 2.51–2.69 Å. In the third Mo+2.53+ site, Mo+2.53+ is bonded to five Se2- atoms to form a mixture of edge and corner-sharing MoSe5 trigonal bipyramids. There are a spread of Mo–Se bond distances ranging from 2.31–2.69 Å. In the fourth Mo+2.53+ site, Mo+2.53+ is bonded in a distorted rectangular see-saw-like geometry to four Se2- atoms. There are a spread of Mo–Se bond distances ranging from 2.55–2.64 Å. In the fifth Mo+2.53+ site, Mo+2.53+ is bonded to five Se2- atoms to form a mixture of distorted edge and corner-sharing MoSe5 trigonal bipyramids.
