Materials Data on CaH8C6S2(NO4)2 by Materials Project
CaCH8O6(C2NS)2CO2 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two formic acid molecules; two thiazolo[5,4-d]thiazole molecules; and one CaCH8O6 cluster. In the CaCH8O6 cluster, Ca2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ca–O bond distances ranging from 2.35–2.62 Å. C+2.67+ is bonded in a bent 120 degrees geometry to two O2- atoms. Both C–O bond lengths are 1.27 Å. There are eight inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the seventh H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to one Ca2+ and one C+2.67+ atom. In the second O2- site, O2- is bonded in a water-like geometry to two equivalent Ca2+ and two H1+ atoms. In the third O2- site, O2- is bonded in a distorted water-like geometry to one Ca2+ and two H1+ atoms. In the fourth O2- site, O2- is bonded in a distorted water-like geometry to one Ca2+ and two H1+ atoms. In the fifth O2- site, O2- is bonded in a distorted water-like geometry to one Ca2+ and two H1+ atoms. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to one Ca2+ and one C+2.67+ atom.
