文摘

Two coordination polymers [Cu(Hpptz)]·H₂O (1) and [Co(Hpptz)(OH)]·H₂O (2) [Hpptz = 5-(4-((1H-pyrazol-1-yl)methyl)-phenyl)-5H-tetrazole] were hydrothermally synthesized and characterized by elemental analysis, IR, PXRD and TGA. 1 and 2 are featured similar 22-membered M₂L₂ rings with close metal pitch and stacking interactions, however, two different 3D supramolecular topological architectures are obtained due to the different coordination modes of the metals. The magnetic and catalytic properties of 2 are also investigated. The results indicate that 2 demonstrates frequency-dependent magnetic behavior and moderate catalytic activity toward Claisen Schmidt reaction of nitrobenzaldehyde and acetone.
