Abstract

Abstract : The three‐dimensional (3D) porous cobalt(II) metal‐organic framework (MOF), [Co3 (L)2 (DMA)2 (MeOH)2 · 4(DMA)· 6(MeOH)] n (1 ) [L = fully deprotonated 2, 7‐bis(4‐benzoic acid)‐ N ‐(4‐benzoic acid) carbazole, DMA = N, N ‐dimethylacetamide], was synthesized by hydrothermal reaction. Based on X‐ray single‐crystal diffraction, structural analysis indicates that complex1 crystallizes in the monoclinic C 2/ c space group. Complex1 possesses a 3, 6‐connected three‐dimensional (3D) topological structure with a point symbol of {4 2 · 6}2 {4 4 · 6 2 · 8 7 · 10 2 } when a trinuclear Co II cluster was regarded as 6‐connected node and the organic ligands could be regarded as 3‐connected linkers between the 6‐connected nodes. The framework structure exhibits a one‐dimension (1D) channel with an accessible void of 4223.0 Å 3, amounting to 42.8 % of the total unit‐cell volume (9862.0 Å 3 ). Moreover, the magnetic properties of complex1 were studied. Abstract :
