Abstract

Three new coordination polymers [Mn4(bptca)2(titmb)(H2O)7]·DMF·4H2O (1), [Ni2(bptca)(titmb)2]·13H2O (2) and [Co2(bptca)(titmb)2]·13H2O (3) were constructed from 4,4′-bipyridine-2,2′,6,6′-tetracarboxylic acid (H4bptca) and 1,3,5-tris(imidazol-1-ylmethyl)-2,4,6-trimethylbenzene (titmb) under hydrothermal conditions. Single crystal X-ray diffraction analysis shows that 1 contains [Mn4(μ2-OCO)4] subunits linked through organic ligands to form a two-dimensional (2D) double-layer structure, while 2 and 3 are isostructural and exhibit a unique three-dimensional (3D) framework with open channels resided by water molecules. The magnetic behavior of 1 and sorption property of 2 have been investigated.
