Abstract AR
تم تحضير و تشخيص و دراسة معقدات جديدة للكوبلت (II) مع خليط من الليكتمدات المتضمنة سالسالديهايد ثايوسميكاربازون-STH2 و الأحماض الكاربوكسيلية-AH2 (حامض السالساليك-SH2 أو الأنثرانيليك-AnH2 أو الفثاليك-PH2).
شخصت المعقدات الناتجة باستخدام تقنيات مختلفة فيزيائية-كيميائية و أستنتج منها أن الليكاندات في أعلاه تعطي معقدات أيونية موجبة أو متعادلة ذات صيغة عامة Co 2 (AH 2) 2 (STH 2) 2 (NO 3) 2 ] (NO 3) 2 أو [Co 2 (AH2) 2 (STH 2) 2 XN] (حيث X = CO3 2- أو CH3 CO 2- و n = 2 أو 4) و اقترحت الدراسة أن المعقدات سداسية التناسق ذات ثماني السطوح و تكون يشكل دايمر(معقدات ثنائية النواة).
Abstract EN
Preparation and characterization of new cobalt (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 [Co2(AH2)2(STH2)2(NO3)2](NO3)2 or [Co2(AH2)2(STH2)2Xn] have been suggested in neutral medium giving either cationic or neutral complexes .
Whereas , in basic medium the formula [Co2(AH)2(STH)2] has 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).
