Abstract

CoH8(S2O5)2(N(CH3)4)2 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four tetramethylammonium molecules and two CoH8(S2O5)2 clusters. In each CoH8(S2O5)2 cluster, Co2+ is bonded in an octahedral geometry to two equivalent S2- and four O2- atoms. Both Co–S bond lengths are 2.49 Å. There are two shorter (2.15 Å) and two longer (2.18 Å) Co–O bond lengths. 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 1.00 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.72 Å) H–O bond length. 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 1.00 Å. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a water-like geometry to one Co2+ and one S2- atom. The S–S bond length is 2.03 Å. In the second S2- site, S2- is bonded in a trigonal non-coplanar geometry to one S2- and three O2- atoms. There are a spread of S–O bond distances ranging from 1.48–1.51 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to one Co2+ and two H1+ atoms. In the second O2- site, O2- is bonded in a distorted water-like geometry to one Co2+ and two H1+ atoms. In the third O2- site, O2- is bonded in a 1-coordinate geometry to one S2- atom. In the fourth O2- site, O2- is bonded in a distorted water-like geometry to one H1+ and one S2- atom. In the fifth O2- site, O2- is bonded in a single-bond geometry to one S2- atom.
