Two temperature-induced isomers of metal-carboxylate frameworks based on different linear trinuclear Co3(RCOO)8clusters exhibiting different magnetic behaviours

Abstract

A pair of structurally isomeric metal-carboxylate frameworks (MCFs) with an identical formula of [Me2NH2]2[Co3(1,4-bdc)4]·4DMF (1 and 2, Me2NH2 = protonated dimethylamine, 1,4-bdcH2 = 1,4-benzenedicarboxylic acid and DMF = N,N′-dimethylformamide) have been synthesized from identical reactants at 160 °C and room temperature, respectively. Although both compounds feature the same bcg net (a uninodal eight-connected net) based on the Co3(OOCR)8 clusters as eight-connected nodes, the isomers exhibit different magnetic behaviours, owing to the slight difference of linear Co3(OOCR)8 clusters.
