Crystal structure ofcis-tetraaquadichloridocobalt(II) sulfolane disolvate

Abstract

In the title compound, [CoCl2(H2O)4]·2C4H8SO2, the CoII cation is located on the twofold rotation axis and is coordinated by four water mol­ecules and two adjacent chloride ligands in a slightly distorted octa­hedral coordination environment. The cisoid angles are in the range 83.27 (5)–99.66 (2)°. The three transoid angles deviate significantly from the ideal linear angle. The crystal packing can be described as a linear arrangement of complex units along c formed by bifurcated O—H⋯Cl hydrogen bonds between two water mol­ecules from one complex unit towards one chloride ligand of the neighbouring complex. Two solvent mol­ecules per complex are attached to this infinite chain via O—H⋯O hydrogen bonds in which water mol­ecules act as the hydrogen-bond donor and sulfolane O atoms as the hydrogen-bond acceptor sites.

Crystal structure of bis(acetonyltriphenylphosphonium) tetrachloridocobaltate(II)

“…Cobalt(II) and cobalt(III) compounds can show a variety of extended structural arrangements and are used as metal catalysts (Adams et al, 2008;Boudraa et al, 2015;Bronova et al, 2013;Dhieb et al, 2014;Lassahn et al, 2003;Luo et al, 2013;Merola et al, 2013). Alkyltriphenylphosphonium cations have been employed as stabilizing cations for a variety of different anions, such as nitrate, tetraphenylborate and bromide (Diop et al, 2013;Evans, 2010;Kavitha et al, 2012).…”
