Synthesis studies of mixed-ligand complexes of some transition elements

الملخص EN

This work presents the synthesis and identification of some mixed, ligand complexes with some transition elementals.

These complexes containing from two to four different ligands.

No report have been found on this work according to the internet informations up to 2003.

The prepared complexes were characterized on the bases of their elemental analyses (C, H, N), metal percentage determination, IR and UV-Vis spectroscopy, conductivity measurements as well as their magnetic moments.

The complexes have been classified into five groups with the general formulae as follows.

1.

[M(CA)4Y2J.

2.

[M(TP)4Y2j.

3.

[M(CA)2(Ad)X2], 4.

[M(TP)2(Ad)X2], 5.

[M(CA)2(TP)2XY].

Where lvT2 = VO+2, Co+2, Ni+2, Cu+2 CA = Caffeine TP= Theophylline Ad= Adenine X= Thiocyanateion (SCN) Y= Cyanate ion (OCN')
