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

A novel linear trinuclear nickel(II) complex, [Ni3(H2O)2(DMA)2(acbshz)2]·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.

The three nickel ions in this novel trinuclear complex arrange in a strictly linear structure, and exhibit alternating square-planar and octahedral coordination environments. It shows a wave-like 2D structure formed by intermolecular H bonds.Figure optionsDownload as PowerPoint slide
