Tris(μ(2)-2-meth­oxy-6-{[(2-sulfido­eth­yl)imino]meth­yl}phenolato)trinickel(II) di­methyl­formamide monosolvate: crystal structure, spectroscopic characterization and anti­bacterial activity

The title trinuclear nickel(II) complex, [Ni(3)(C(10)H(11)NO(2)S)(3)]·C(3)H(7)NO, with a Schiff base ligand formed in situ from 2-amino­ethane­thiol and o-vanillin crystallizes in the ortho­rhom­bic space group Pbca. Its asymmetric unit consists of one neutral Ni(3) L (3) mol­ecule and one DMF solvent mol­ecule. The solid-state organization of the complex can be described as an insertion of the solvent mol­ecules within the crystallographically independent trinuclear Ni(II) species. Several C—H⋯π edge-to-face inter­actions and π–π stacking inter­actions link the components in the crystal. A first example of a short inter­molecular C—H⋯Ni contact is found. Anti­bacterial in vitro screening revealed that the title compound has anti­bacterial activity, the best effect being against Acinetobacter baumannii.
