Abstract AR
تم في هذا البحث تحضير و دراسة معقدات Cr (III) , Fe(III) ،Co(II) ،Ni(II) ,Cu(II) مع (-2-3 هيدروكسي فنيل) -2- بايروزولين في الوسط المائي).
شخصت هذه المعقدات باستخدام القياسات الطيفية UV-visible، IR، و قياسات التوصيل المولاري.
و قد تم الاستنتاج أن ارتباط الليكند الثنائي السن من خلال أحدى ذرتي نيتروجين البايرازول و ذرة أوكسجين مجموعة الفينيل و تم اقتراح الصيغة التركيبية للمعقدات.
Abstract EN
Transition metal complexes Cr (III), Fe (III), Co (II), Ni (II) & Cu (II) with 3-(2 hydroxy phenyl) 2– pyrazoline have been prepared and characterized in aqueous solution.
The complexes were characterized by infrared (IR), UV-visible & molar conductivity measurements.
The bidentate ligand was bonded from one of the nitrogen atoms of pyrazolien & oxygen atom phenoxide group.
The molecular structure for the complexes was proposed.
The stability constants of these complexes were found by measuring electric molar conductivity in different concentrations was also found.
The determined values of the prepared complexes increases according to the following sequence : Co+2 > Cu+2 > Ni+2 > Fe+3 > Cr+3 This result agrees with the Irving Williamson series.
