【摘要】Five new metal transition metal complexes formed with tripodal polyimidazole

ligand

tri{2-[2-(1-((min)3tren),

methyl)imidazoly](methylimino)ethyl}amine

[Zn(min)3tren](ClO4)2 (1) [Cu(min)3tren](ClO4)2 (2), [Ni(min)3tren]-(ClO4)2

(3),

[Co(min)3tren](ClO4)2

(4),

and

[Mn(min)3tren](ClO4)2·CH3CN (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 [MN6] octahedra, are coordinated with three imine nitrogen atoms and three imidazole nitrogen atoms. 【总页数】5页(132-136)
