The crystal structure of a trinuclear Ni II complex with a Schiff base ligand formed in situ from cysteamine (2-aminoethanethiol) and o-vanillin is reported as well results of its antibacterial activity screening.
The title trinuclear nickel(II) complex, [Ni 3(C 10H 11NO 2S) 3]·C 3H 7NO, 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.
