Abstract

The reaction of cobalt(II) chloride with 2-hydroxypyridine (Hhp) and lithium pivalate in acetonitrile affords the 1D polymer [Li3CoCl(μ-Piv)(μ3-Piv)2(μ3,η2-Piv)(μ-Hhp)2(η1-HPiv)] n , in which the repeating units are linked by bridging pyridone molecules. The reaction of cobalt nitrate hexahydrate with 2-hydroxy-6-methylpyridine (Hmhp) in the presence of the deprotonating agent (Et3N) resulted in the crystallization of the 1D polymer of the composition [Li2Co7(μ3-OH)2(μ3-Piv)3(μ-Piv)2(μ3,η2-mhp)5(μ,η2-mhp)2(μ3-mhp)(μ,η2-NO3)·2MeCN] n , in which the bulky metal fragments {Li2Co7(OH)2(Piv)5)(mhp)8} are linked together through the lithium atoms by chelate bridging nitrate anions. The resulting 1D polymers were characterized by X-ray diffraction, and their magnetic properties were investigated.
