description: (W)2Ca3W6B5O13Cl2 crystallizes in the monoclinic Pc space group. The structure is two-dimensional and consists of four wolfram molecules and one Ca3W6B5O13Cl2 sheet oriented in the (0, 1, 0) direction. In the Ca3W6B5O13Cl2 sheet, there are three inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Ca–O bond distances ranging from 2.18–2.98 Å. In the second Ca2+ site, Ca2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Ca–O bond distances ranging from 2.27–2.60 Å. In the third Ca2+ site, Ca2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ca–O bond distances ranging from 2.28–2.58 Å. There are six inequivalent W+2.38+ sites. In the first W+2.38+ site, W+2.38+ is bonded in a single-bond geometry to one O2- atom.

In the fourth B+0.60+ site, B+0.60+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of B–O bond distances ranging from 1.35–1.41 Å. In the fifth B+0.60+ site, B+0.60+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.35 Å) and one longer (1.42 Å) B–O bond length. There are thirteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to one Ca2+, one W+2.38+, and one B+0.60+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two Ca2+ and one B+0.60+ atom.
