Five new metal transition metal complexes formed with tripodal polyimidazole ligand tri{2‐[2‐(1‐methyl)imi‐dazoly](methylimino)ethyl}amine ((min) 3 tren), [Zn(min) 3 tren](ClO 4 ) 2 ( 1 ) [Cu(min) 3 tren](ClO 4 ) 2 ( 2 ), [Ni(min) 3 tren]‐(ClO 4 ) 2 ( 3 ), [Co(min) 3 tren](ClO 4 ) 2 ( 4 ), and [Mn(min) 3 tren](ClO 4 ) 2 ·CH 3 CN ( 5 ) were synthesized and characterized by elemental analysis, molar conductances, IR and electronic spectra. Analytical results show 1:1 metal‐ligand stoichiometry and 2:1 type of electrolyte in all metal complexes. The crystal structures of 4 and 5 have been determined. The metal atoms in 4 and 5 , being in distorted [MN 6 ] octahedra, are coordinated with three imine nitrogen atoms and three imidazole nitrogen atoms.
