Abstract
In this paper, the crystal structures and preliminary magnetic properties of two new molecule-based magnets, Mn[N(CN)2]2(H2O)2(2,5-me 2pyz)2 (1) and Mn[N(CN)2]2(H2O)(NH2-pyz) 1.5 (2) (pyz = pyrazine) are reported. The structure of 1 consists of 2D Mn[N(CN)2]2(H2O)2 layers which are hydrogen bonded together by the 2,5-me2pyz ligands while that of 2 forms a novel 1D ladder structure with μ1.5-[N(CN)2]- rungs. Magnetically, 1 exhibits a spin canted phase transition at 1.78 K while 2 remains paramagnetic down to 1.7 K.
