الملخص EN

In this paper a series of new mono and heterometallic Ni(II) complexes of the general formula[Ni(3-Hophdtc)2],[Ni(Ag(3-Hophdtc)2}2],NiLn(Ag(3-Hophdtc)2}2],NiM(3- Hophdtc)4] ,[Ni(L)nM(3-Hophdtc)4].3-Hophdtc=3-hydroxy phenyl dithiocarbamate.when n = 2,L quinoline,4-picoline,when n = 3,L = ethylenediamine ,1,10 phenanthroline, M=Zn+2,Cd+2.

All the isolated complexes have been characterized by atomic absorption , elemental analysis,molar conductivity , Infrared , electronic absorption spectra and magnetic measurement.The conductivity measurements proved the non-electrolytic behaviour of all the compounds, suscetptibility measurements and electronic spectra shows a tetrahedral geometry for complexes of the type [Ni(3-Hophdtc)2],[Ni(Ag(3-Hophdtc)2}2], NiM(3- Hophdtc)4] and octahedral geometry for complexes of the type NiLn(Ag(3- Hophdtc)2}2],[Ni(L)nM(3-Hophdtc)4]
