Hydrothermal Synthesis of Three Novel Multidimensional Metal−Organic Frameworks with Unusual Units and Mixed Ligands

Abstract

The hydrothermal reactions of 1,2,4-benzenetricarboxylate (H3btrc), 4,4‘-bipyridine (4,4‘-bpy), or 1,10-phenanthroline (1,10-phen) with transition metal acetates in basified solvent gave rise to three novel coordination polymers, [Ni3(btrc)2(4,4‘-bpy)2(H2O)5]n·2nH2O (1), [Cu3(btrc)2(1,10-phen)3]n (2), and [Co(H2btrc)2(4,4‘-bpy)3(H2O)2]n (3), which show respectively three-dimensional polymeric architecture, two-dimensional lamella, and one-dimensional chain architecture. Interestingly, the noncentrosymmetric compound 1 is constructed by beautiful “S” ribbons and exhibits very interesting ferromagnetic properties.
