Tris(μ2-2-meth­oxy-6-{(2-sulfido­eth­yl)iminometh­yl}phenolato)trinickel(II) di­methyl­formamide monosolvate: crystal structure spectroscopic characterization and anti­bacterial activity

摘要

The title trinuclear nickel(II) complex, [Ni3(C10H11NO2S)3]·C3H7NO, 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 Ni3 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.
