| Abstract: | Two copper(II) complexes, Cu2{3,5-(NO2)2sal}2(2,2′-bipy)2 · 0.5H2O (1) and Cu2{3,5-(NO2)2sal}2(4,4′-bipy)(H2O)2]n (2) (3,5-(NO2)2sal = 3,5-dinitrosalicylate, 2,2′-bipy = 2,2′-bipyridine, 4,4′-bipy = 4,4′-bipyridine), were synthesized by hydrothermal reactions and characterized by single crystal X-ray analysis. There are discrete cyclic binuclear structure in 1 and 2D herringbone-like network structure in 2, although bridging ligand 3,5-(NO2)2sal in 1 and 2 has same coordination model. Variable temperature magnetic measurement reveals small ferromagnetic interactions in complex 1. |
