A New Mannich base [N-(4-morpholinomethyl)-1, 8-naphthalimide] (L), was synthesized and characterized by C.H.N analysis, FTIR, UV-Vis and 1HNMR spectral analysis. Metal ion complexes of (L) with Pt(IV), Rh(III), Ru(III) and Pd(II) ions were prepared and characterized by FT-IR, and UV-Vis spectroscopy, elemental analysis (C.H.N), flame atomic absorption techniques as well as magnetic susceptibility and conductivity measurements. The results showed that metal ion complexes for all complexes were found in [1:2] [M:L] ratio except for Pd(II) complex which was found in [1:1] [M:L] ratio. Hyperchem-8 program has been used to predict structural geometries of the (L) and it's complexes in gas phase. The electrostatic potential (EP) of the (L) was calculated. Furthermore, the heat of formation (∆Hf^o), binding energy (∆Eb), vibration spectra, electronic spectra and bond length for the ligand (L) and its metal ion complexes were calculated by PM3 methods. The antimicrobial activity of (L) and its complexes has been extensively studied against pathogenic bacteria such as (Pseudonomous aerugionosa) as gram negative and (Bacillus Subtilis) as gram positive and fungi (Candida albicans) and (Aspergillus flavus) by agar-well diffusion technique.

تم تحضير قاعدة مانخ الجديدة [N-(4- مورفولينومثيل)-8,1- نفثال ايمايد] (L) والتي شخصت باستخدام التحليل الدقيق للعناصر(C.H.N) وطيف الاشعة تحت الحمراء (FT-IR) وطيف الرنين النووي المغناطيسي (H.NMR1). حضرت معقدات الليكاند (L) مع ايونات العناصر Pd(II), Ru(III), Rh(III) ] Pt(IV) ] والتي شخصت باستخدام اطياف الاشعة تحت الحمراء وفوق البنفسجية – المرئية والتحليل الدقيق للعناصر (C.H.N) والامتصاص الذري اللهبي بالاضافة الى قياسات التوصيلية الكهربائية والحساسية المغناطيسية . اظهرت النتائج ان المعقدات المحضرة كانت بنسبة [2:1] [L:M] مع [Ru(III), Rh(III), Pt(IV) ] ماعدا مع [Pd(II)] كانت النسبة [1:1] [L:M]. استخدم برنامج (8-Hyperchem) لاستنتاج التراكيب الهندسية لكل من الليكاند (L) ومعقداته في الطور الغازي . تم حساب الجهد الالكتروستاتيكي (Ep) لليكاند (L) , بالاضافة الى ذلك تم حساب حرارة التكوين (∆Hf°) وطاقة التاصر (∆Eb) والتردد الاهتزازي والاطياف الالكترونية واطوال الاواصر لليكاند (L) ومعقداته باستخدام الدالة (PM3) و تم تقيم الفعالية لليكاند (L) ومعقداته ضد البكتريا (Pseudonomous aerugionosa) السالبة لصبغة كرام و (Bacillus Subtilis) الموجبة لصبغة كرام و الفعالية المضادة للفطريات باستخدام النوعين (Candida albicans) و Aspergillus flavus)) باستخدام تقنية التنافذ .
