Abstract AR
حضرت معقدات الكوبلت (II) مع مزيج من الليكندات التي تتضمن 4-هيدروكـسي بنزالديهايد سميكاربازون (HBSCH) و استرات الأحماض الامينية (A) [فينول كلايسين استر(GlyP) و فينول الانين استر (AlaP) و 2- امينو فينول كلايسين استر (GlyA) و 2-امينو فينول الانين استر (AlaA)].
و شخصت باستخدام تقنيات فيزيائية-كيميائية.
اقترحت الـصيغ و [Co(HBSCH)(A)2(NO3)2] و [Co(HBSCH)(A)2(NO3)]NO3 العامــــــة المحضرة للمعقدات [Co(HBSCH)2(A) (NO3)2] و [Co(HBSCH)2(A)(NO3)]NO3 فـي الوسـط المتعـادل.
فـي حـين اقترحـت الـصيغ العامـة [Co(HBSC)(A)2] و [(Co(HBSC)2(A] للمعقدات المحضرة في الوسط القاعـدي (حيـث HBSC = الليكانـد HBSCH مزال منه بروتون أو بروتونين).
اقترحت الدراسة أن جميع المعقدات ذات بنيـة ثمانية السطوح.
Abstract EN
Cobalt (II) complexes with mixed ligands including 4-hydroxybenzaldehyde semicarbazone (HBSCH) and esters of amino acids -A {phenol glycine ester (GlyP), phenol alanine ester (AlaP), 2-aminophenol glycine ester (GlyA) and 2-aminophenol alanine ester (AlaA)} have been prepared and characterized by physical chemical techniques.
General formulaes [Co(HBSCH)(A)2(NO3)]NO3, [Co(HBSCH)(A)2(NO3)2], [Co(HBSCH)2(A)(NO3)]NO3 and [Co(HBSCH)2(A)(NO3)2] have been proposed for the complexes prepared in neutral medium.
Whereas, the formulaes [Co(HBSC)(A)2] and [Co(HBSC)2(A)] have been proposed for the complexes prepared in basic medium (where HBSC = deprotonated HBSCH ligand).
The study suggested that all the complexes had octahedral geometries.
