Abstract :The novel phenolic Mannich bases 2,2`-insert ignore into journalissuearticles values(2-hydroxy-4,5- dimethylbenzylazanediyl);diethanol insert ignore into journalissuearticles values(1); and 2-insert ignore into journalissuearticles values(insert ignore into journalissuearticles values(2-insert ignore into journalissuearticles values(4-insert ignore into journalissuearticles values(2-hydroxy-4,5- dimethylbenzyl);piperazin-1-yl);ethylamino);methyl);-4,5-dimethylphenol insert ignore into journalissuearticles values(2); have been synthesized in good yield by using a microwave-induced technique from 3,4-dimethylphenol and corresponding amines in the presence of formaldehyde. Metal complexes of 1 and 2 for Niinsert ignore into journalissuearticles values(II); insert ignore into journalissuearticles values(3 and 5); and for Cuinsert ignore into journalissuearticles values(II); insert ignore into journalissuearticles values(4 and 6); have also been prepared and all compounds have been characterized by elemental and spectral analyses. Thermal, magnetic, and electronic studies have also been reported for metal complexes. Electronic spectra and magnetic susceptibility measurements suggested tetrahedral geometry for Niinsert ignore into journalissuearticles values(II); insert ignore into journalissuearticles values(3);, square planar geometry for Cuinsert ignore into journalissuearticles values(II); insert ignore into journalissuearticles values(4); complexes of 1, and octahedral geometries for both Niinsert ignore into journalissuearticles values(II); insert ignore into journalissuearticles values(5); and Cuinsert ignore into journalissuearticles values(II); insert ignore into journalissuearticles values(6); complexes of 2.
