Four novel Cobalt(Ⅱ) complexes have been synthesized and characterized, namely [Co2(4I-TPHA)(L) 4 (ClO4)2 (L denotes 1, 10-phenanthroline(phen)(1), 5-nitro1, 10-phenanthroline(NO2-phen)(2), 2,2'- bipyridyl(bpy) (3) and 4. 4'-dimethyl-2, 2'bipyridyl (Me2bpy) (4). respectively),where 4I- TPHA is the tetraiodoterephthalate dianion. The magnetic studies indicate that a weak antiferromagnetic spin exchange imteraction exists between the metal ions.

Key words: Binuclear compexes cobalt(II)-Cobalt(II), Tetraiodoterephthalate dianion, Antiferromagnetic interaction
