Abstract
Abstract Three new coordination polymers, [Co(HBit) 2 ] n ( 1 ), [Mn(HBit) 2 ] n ( 2 ) (H 2 Bit = 2-((1H-tetrazol-5-yl)methyl)-1H-benzo[d]imidazole), and [CdCl(MBi)(HMBi)] n ( 3 ), (HMBi = 2-methyl-1H-benzo-[d]imidazole), have been hydrothermally synthesized via in situ ligand reaction. Compounds 1 and 2 are isomorphous and display interesting 3D chiral supramolecular frameworks constructed from one-dimensional 4 1 helical chains. Complex 3 possesses a one-dimensional coordination chain, which is further connected to a 2D layer by intermolecular hydrogen bonds. More interestingly, both H 2 Bit and HMBi ligands are in situ generated from the same precursor, 2-(1H-benzo[d]imidazol-2-yl)-acetonitrile, and the formation may depend on the kind of metal ion. Furthermore, the solid-state luminescence of complex 3 was investigated at room temperature.
