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.

Graphical abstractThe 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 full-size imageDownload as PowerPoint slide
