Abstract

CoH8(S2O5)2(N(CH3)4)2 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of four tetramethylammonium molecules and one CoH8(S2O5)2 sheet oriented in the (1, 0, 0) direction. In the CoH8(S2O5)2 sheet, Co2+ is bonded in a square co-planar geometry to two equivalent S2- and two equivalent O2- atoms. Both Co–S bond lengths are 2.26 Å. Both Co–O bond lengths are 2.22 Å. There are four 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 1.02 Å. In the second H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.67 Å) H–O bond length. In the third H1+ site, H1+ is bonded in a distorted single-bond geometry to one S2- and one O2- atom. The H–S bond length is 1.76 Å. The H–O bond length is 1.13 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one S2- and one O2- atom. The H–S bond length is 2.01 Å. The H–O bond length is 1.03 Å. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of S–O bond distances ranging from 1.49–1.66 Å. In the second S2- site, S2- is bonded in a 3-coordinate geometry to one Co2+ and two H1+ atoms. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a water-like geometry to one H1+ and one S2- atom. In the second O2- site, O2- is bonded in a distorted water-like geometry to one H1+ and one S2- atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one Co2+ and one H1+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one H1+ and one S2- atom. In the fifth O2- site, O2- is bonded in a single-bond geometry to one H1+ atom.
