Abstract

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.
