A new series of transition metal complexes of Co(III), Ni(II) and VO(IV) was synthesized with the bidentate Schiff base ligand (HL) derived from the condensation of 2-amino-3-benzyloxypyridine and 5-bromo salicylaldehyde. | Synthesis spectroscopic characterization crystal structure and Hirshfeld surface analysis of Co III Ni II and VO IV metal complexes with a novel Schiff base ligand and their antimicrobial activities Current Chemistry Letters 8 2019 39 52 Contents lists available at GrowingScience Current Chemistry Letters homepage www.GrowingScience.com Synthesis spectroscopic characterization crystal structure and Hirshfeld surface analysis of Co III Ni II and VO IV metal complexes with a novel Schiff base ligand and their antimicrobial activities Disha Sharmaa and Hosakere D. Revanasiddappaa a Department of Chemistry University of Mysore Manasagangothri Mysuru 570 006 Karnataka India CHRONICLE ABSTRACT Article history A new series of transition metal complexes of Co III Ni II and VO IV was synthesized with Received September 3 2018 the bidentate Schiff base ligand HL derived from the condensation of 2-amino-3- Received in revised form benzyloxypyridine and 5-bromo salicylaldehyde. The synthesized Schiff base ligand and its November 18 2018 metal complexes C1-C6 were structurally characterized by satisfactory elemental analysis Accepted December 18 2018 spectral studies such as Mass IR 1H and 13C NMR conductance measurement UV-vis and Available online magnetic measurements and thermal studies. The structure of HL was authenticated by X-ray December 19 2018 single-crystal analysis. Hirshfeld surface analysis was carried out to understand the nature of Keywords intermolecular contacts the fingerprint plot provides the information about the percentage Schiff base contribution. Square-pyramidal geometry is proposed for VO IV complexes whereas Metal complexes octahedral geometry for Co III and Ni II complexes. The Schiff base ligand and its metal X-ray crystal structure complexes have been tested in vitro for their antibacterial activities by using well diffusion Hirshfeld surface analysis method against Gram positive bacteria B. subtilis S. aureus and Gram negative bacteria S. .
