Materials Data on CoH8S2(NO2)4 by Materials Project

Abstract

Co(SO4)2(NH2)4 crystallizes in the triclinic P1 space group. The structure is one-dimensional and consists of four ammonia molecules and one Co(SO4)2 ribbon oriented in the (1, 0, 0) direction. In the Co(SO4)2 ribbon, Co2+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Co–O bond distances ranging from 2.03–2.08 Å. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of S–O bond distances ranging from 1.47–1.53 Å. In the second S2- site, S2- is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of S–O bond distances ranging from 1.47–1.52 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Co2+ and one S2- atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one Co2+ and one S2- atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Co2+ and one S2- atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Co2+ and one S2- atom. In the fifth O2- site, O2- is bonded in a single-bond geometry to one S2- atom. In the sixth O2- site, O2- is bonded in a single-bond geometry to one S2- atom. In the seventh O2- site, O2- is bonded in a single-bond geometry to one S2- atom. In the eighth O2- site, O2- is bonded in a single-bond geometry to one S2- atom.
