In the first Ca2+ site, Ca2+ is bonded in a 7-coordinate geometry to seven S2- atoms. There are a spread of Ca–S bond distances ranging from 2.71–3.36 Å. In the second Ca2+ site, Ca2+ is bonded in a 7-coordinate geometry to seven S2- atoms. There are a spread of Ca–S bond distances ranging from 2.72–2.99 Å. In the third Ca2+ site, Ca2+ is bonded in a 7-coordinate geometry to seven S2- atoms. There are a spread of Ca–S bond distances ranging from 2.75–3.11 Å. In the fourth Ca2+ site, Ca2+ is bonded in a 7-coordinate geometry to seven S2- atoms. There are a spread of Ca–S bond distances ranging from 2.80–3.15 Å. There are five inequivalent Sn4+ sites. In the first Sn4+ site, Sn4+ is bonded in a distorted rectangular see-saw-like geometry to four S2- atoms. There are a spread of Sn–S bond distances ranging from 2.63–3.04 Å.

In the fifth S2- site, S2- is bonded in a 4-coordinate geometry to two Ca2+, one Sn4+, and one S2- atom. The S–S bond length is 2.14 Å. In the sixth S2- site, S2- is bonded to three Ca2+ and one Sn4+ atom to form distorted edge-sharing SCa3Sn trigonal pyramids. In the seventh S2- site, S2- is bonded in a 5-coordinate geometry to two Ca2+, two Sn4+, and one S2- atom. The S–S bond length is 2.10 Å. In the eighth S2- site, S2- is bonded to two Ca2+ and three Sn4+ atoms to form distorted SCa2Sn3 square pyramids that share an edgeedge with one SCa2Sn3 square pyramid and an edgeedge with one SCa3Sn trigonal pyramid. In the ninth S2- site, S2- is bonded in a 4-coordinate geometry to three Ca2+ and one S2- atom. In the tenth S2- site, S2- is bonded in a distorted trigonal planar geometry to one Ca2+ and two Sn4+ atoms. In the eleventh S2- site, S2- is bonded in a 4-coordinate geometry to two Ca2+, one Sn4+, and one S2- atom. In the twelfth S2- site, S2- is bonded in a 2-coordinate geometry to three Ca2+ and one S2- atom. In the thirteenth S2- site, S2- is bonded in a rectangular see-saw-like geometry to three Ca2+ and one Sn4+ atom.
