Abstract
A new series of 21-membered macrocyclic complexes [MLX2] [M=Mn(II), Co(II), Ni(II), CU(II) and Zn(II); X=Cl or NO3] has been synthesized by template r eaction of phthalaldehyde with hydrazine hydrate and 2,4-pentanedione in me thanol The over-all Geometry and stereochemistry of these complexes have be en elucidated by IR, H-1 NMR, EPR, UV-vis, magnetic susceptibility and cond uctance values. An octahedral geometry around the metal ion is suggested fo r all the complexes.
