1 Source of materials

The Schiff base ligand named 6,6′-((1E,1′E)-(ethane-1,2-diylbis(azaneylylidene)) bis(methaneylylidene)) bis(2-methoxyphenol) was prepared according to the literature [3]. The Schiff base ligand (0.1 mmol, 32.8 mg) was dissolved in 10 mL of methanol. The CoCl2·6H2O (0.1 mmol, 23.7 mg) and 4-hydroxybenzenesulfonic acid sodium salt (0.2 mmol, 39.3 mg) were added to the above solution. This mixture was stirred for 3 h and then filtered, resulting in an orange coloured solution. Crystals of the title compound were obtained by slow evaporation within two weeks.

2 Experimental details

All hydrogen atomic positions were taken from a difference Fourier map. Hydrogen atoms were assigned with common isotropic displacement factors Uiso(H) = 1.2 times Ueq (C, phenyl ring and methylene carbon) and Uiso(H) = 1.5 times Ueq(C, methyl carbon). All the H atoms were refined as riding on their parent atom.

3 Comment

Recently, coordination compounds composed of sulfonic acid have received considerable attention due to their appealing properties and prospective uses in adsorption and separation processes [4], [5], [6], [7], [8]. Sulfonate ligands with acidic –SO3H groups possess robust coordination ability, leading to an enhanced range of potential geometric arrangements between O-donors and metal ions, resulting in the formation of numerous structures [9, 10]. As a part of our current research on the exploration of functional coordination complexes, we report a new coordination compound based on sulfonate ligands.

The asymmetric unit of the title structure contains one Schiff base ligand, one Co(II) ion, one Na(I) ion, one 4-hydroxybenzenesulfonate and one coordinated methanol molecule. The Co centre is four coordinated with two O atoms and two N atoms from the Schiff base ligands. The Na centre is six-coordinated with four O atoms from the Schiff base ligands, one O atom from the sulfonate and one O atom from coordinated methanol. The bond lengths for Co–O/N in title compound range from 1.811(4) to 1.819(5) Å, and the bond lengths for Na–O range from 2.291(5) to 2.517(4) Å. The bond lengths within these moieties are in the expected ranges [11], [12], [13].
