الملخص

یتضمن هذا البحث تحضیر معقدات محضرة من فلز النحاس(II)، مع لیکاندات قواعد شف وهی:
L1 (benzylideneamino)pyrimidin-2(1H)-one),          
L2(Z)-4-((2-hydroxybenzylidene)amino)pyrimidin-2(1H)-one),
L[4,4'-((1E,1'E)-pentane-2,4-diylidenebis(azanylylidene))bis(pyrimidin-2(1H)-one)]            
حُضرت اللیکندات من تفاعل تکاثف لکل من ألبنزالدیهاید، ألسالسالدیهاید والأسیتایل-أسیتون مع السایتوسین على التوالی. تم تحلیل وتشخیص هذه المُرکبات بواسطة تحلیل ألعناصر، ألتوصیلیة المولاریة، قیاسات ألحساسیة المغناطیسیة، طیف الرنین النووی المغناطیسی، طیف ألأشعة تحت-ألحمراء، ألأَطیاف الألکترونیة. المعقدات المُحضرة صنفت إلى قسمین وهی :

[CuL1Cl2]  , [CuL2Cl2] ,  [CuL3Cl2
[Cu(L1)2Cl2] , [Cu(L2)2Cl2] , [Cu(L3)2Cl2]  

بینت القیم المنخفضة للتوصیلیة المولاریة فی ثنائی مثیل سلفوکساید بان المعقدات المحضرة غیر الکترولیتیة ومن قیاسات الحساسیة المغناطیسة والاطیاف الألکترونیة بان المعقدات المحضرة من النوع(1) أعطت اشکال مربع مستوی لِمعقدات النحاس, أما معقدات النوع((2 فأعطت اشکال ثمانیة السطوح.
