Synthesis, characterization and antibacterial activities of nickel(II) and copper(II) complexes of an N-pendent cyanoethyl derivative of a tetraazamacrocycle

Cadmium(II) compounds of the bis-cyanoethyl derivative (LCX) of Me8[14]aneC (LC): characterization and antibacterial studies

“…Microanalysis (CHNS) were determined on a CHNS-932 elemental analyzer; melting point determinations were made on a electrothermal The parent octamethyl substituted ligand salt, L⋅2HClO 4 , and three isomers L A , L B , and L C of its reduced analogue were prepared as per literature methods [15,21]. Moreover, the 1,8-N-pendant derivative ligand, L CX , from L C , has been synthesized (Scheme 1) as recently reported by our group [17].…”

“…A significant number of metal complexes of different macrocycles [18,19,20], including, those relevant to the present investigation, 14-membered octamethyl tetraazamacrocyclic diene ligand (Me 8 [14] diene), isomeric ligands (L A , L B , and L C ) and their N-pendent derivative ligands, are available in the literature [21,22,23,24,25,26]. In this context, copper(II) and nickel(II) complexes with bis-hydroxyethyl (L BY and L CY ) and dimethyl (L BZ and L CZ ) derivatives of the isomeric ligands L B and L C have been studied [23,24].…”
