摘要

A couple of metal-organic frameworks (MOFs) constructed from rigid bicarboxylates are presented herein, namely, Co 3(ndc) 3(bbi)(CH 3CN) 2 (1) and Dy 2Mn 3(ndc) 6(bipy) 2 (2), where H 2ndc = 2,6-naphthalenedicarboxylic acid, bipy = 2,2′-pyridine, and bbi = 1,1′-(1,4-butanediyl)bis(imidazole). These two coordination polymers have been prepared through solvo/hydrothermal reactions and characterized by single-crystal X-ray study, TG, IR, and elemental analysis. Polymer 1 features a novel self-penetrating network mediated by flexible long-chain ligand and well defines a unique 4 16·5 8·6 4 topology with the treatment of Co 3 unit as an 8-connected node, which equals the highest connectivity for monometallic self-penetrating system so far. Polymer 2 represents the first example of a Mn II-Dy III (3d-4f) heteropentanuclear complex showing an intriguing 3-D 3 6·4 18·5 3·6 framework upon the assignment of Dy 2Mn 3 cluster to an 8-connected node. In addition, magnetic studies of 1 reveal that the antiferromagnetic behavior is operative within the trimeric Co 3 cluster and 2 demonstrates dominant ferromagnetic coupling interactions between Dy III and Mn IIions.
