Preparation and study of some binuclear nickel (II)‎ complexes containing mixed ligands (Salicylaldehyde Thiosemicarbazone and Carboxylic Acid)‎

Abstract EN

Preparation and characterization of new nickel (II) complexes with mixed ligands including salicylaldehyde thiosemicarbazone-STH2 and carboxylic acid-AH2 {salicylic acid-SH2 or anthranilic acid-AnH2 or phthalic acid-PH2} have been studied .

The resulted complexes were characterized using different physico-chemical methods from which the general formulaes [Ni2(AH2)2(STH2)2(NO3)2](NO3)2 or [Ni2(AH2)2(STH2)2Xn] have been suggested in neutral medium .

Whereas, in basic medium the formula [Ni2(AH)2(STH)2] have been proposed {where X = CO3 2- or CH3CO2 - , n = 2 or 4} .

The study suggested that the complexes had octahedral geometries forming dimer (binuclear complexes) .
