Synthesis, crystal structure and bioactivity of a novel linear trinuclear nickel(II) complex

A novel linear trinuclear nickel(II) complex, [Ni-3(H2O)(2)(DMA)(2)(acbshz)(2)]center dot 2DMF (DMA = dimethylamine; acbshz = N-acryloyl-5-bromosalicylhydrazide), has been prepared by self-assembly approach. The three nickel atoms arrange in a strictly linear structure, adjacent molecules are linked by intermolecular H bonds to form a 2D infinite wave-like structure. Antibacterial screening data indicate the formation of the trinuclear complex reduced the antimicrobial activity of the ligand. (c) 2007 Elsevier B.V. All rights reserved.
