A new ligand, 3,3′-di(pyrazinamoyl)-2,2′-bipyridine, L3H2 was prepared and is comprised of distinct binding domains capable of facilitating the formation of coordination polymers. Reaction of L3H2 with [Cu2(OAc)4(H2O)2] in the presence of Et3N·HCl affords {[Cu3(L3)(Cl)(OAc)3]·H2O·MeOH}n (1) in which the [L3]2- anion binds two unique copper ions in a bis-tridentate fashion via amide and pyridyl N atoms. This bimetallic unit is linked to an equivalent unit via a pair of 1,3-acetato and μ-chloro bridges to afford a tetrameric [Cu4(L3)2Cl2(OAc)2] core. Coordination of one of the pyrazole substituents from each ligand to a third copper center of a rigid paddlewheel [Cu2(OAc)4] unit leads to a unique 1-dimensional polymeric structure. Magnetic studies of 1 reveal that the magnetism can be described in terms of two sets of exchange interactions; strong antiferromagnetic interactions between the two copper centers within the paddle-wheel (J/k = -190 K) and a combination of weaker ferro- and antiferro-magnetic interactions within the tetrameric core (J’/k = -5.7 K and J”/k = +2.1 K). The experimental process involved the reaction of [2,2′-Bipyridine]-3,3′-diamine(cas: 75449-26-2).Recommanded Product: 75449-26-2
