Synthesis, structure, thermal and magnetic properties of new tetranuclear copper(II) complex supported by multidentate ligand and glutarate functionality

Structures and Properties of a Series of High-Spin [CoII2] Complexes Supported by Ancillary Benzoate, Ortho-Hydroxybenzoate, and Para-Hydroxybenzoate Ligands

“…This versatility of the carboxylate group as a ligand has oriented its use to build an extended family of coordination complexes showing potential applications as magnetic materials . Again, continuing our research on biological activities of metal complexes of carboxylate-based ligands, we have also reported anticancer, antidiabetic, antibiofilm, and glycosidase/phosphatase activities of iron­(III), nickel­(II), copper­(II), and zinc­(II) complexes. ,− The multidentate ligand, N , N ′-bis­[2-carboxybenzomethyl]- N , N ′-bis­[2-pyridylmethyl]-1,3-diaminopropan-2-ol (H 3 cpdp) incorporating two benzoate and two pyridine functionalities, has been well-established in studying coordination complexes with diverse applications in biological activities and magnetic properties. − ,− Therefore, motivated by our ongoing research interests in designing of smart scaffolds for exploration of magnetic and biological features in a synchronized manner, we extended our attention to synthesize a new family of high-spin cobalt­(II) complexes. In the present contribution, we report the syntheses, X-ray crystal structures, variable temperature magnetic properties, and in vitro antibacterial activities of a series of high-spin dinuclear cobalt­(II) complexes [Co 2 (cpdp)­(μ-O 2 CC 6 H 5 )] ( 1 ), [Co 2 (cpdp)­(μ- o -O 2 CC 6 H 4 (OH))]·H 2 O ( 2 ), and [Co 2 ­(cpdp)­(μ- p -O 2 ­CC 6 ­H 4 ­(OH))]·5H 2 O ( 3 ).…”
