and CO2 from main structure. At the second decomposition
step, C6H6 and CN left from the residue structure at 250–
400 °C. As finally decomposition step, at 400–700 °C,
leaves C6H6, C2H4 and CO groups. For this complex,
although the total weigh lost was theoretically calculated to
be 65.93%, it was observed experimentally to be 69.45%.

Conclusion
In this study, new Tripodal Schiff base ‘‘1,3,5-Tris(4-
(4-carboxyphenyliminomethyl)phenoxymethyl)benzene’’
were synthesized. Synthetic strategy for preparing Tripodal–
Trinuclear uses a complex as a ‘‘ligand’’ that contains a
potential donor group capable of coordinating to the other
ligand. We have chosen [{Fe(salen/salophen)}2O] and
[{Cr(salen/Salophen)}2O] as ‘‘ligand complexes’’ because
they can coordinate to the other ligand. These complexes are
the examples of Tripodal–Trinuclear complexes bridged by
carboxylate anions to the iron and chromium centers. Their
structures were characterized by means of elemental analy-
1
sis, H-NMR, FT-IR spectroscopy, thermal analyses and
magnetic susceptibility measurements. The magnetic data
for the Tripodal–Trinuclear complexes show well agreement
with the d5 and d3 metal ion in an octahedral structure.
