Description
Summary:Two mixed-ligand transition metal coordination polymers, {[Co(aip)(bbp)]·(H 2 O)} n ( 1 ) and {[Ni 2 (aip)(Hbbop) 2 ]·(H 2 O) 2 } n ( 2 ) (H 2 aip = 5-aminoisophthalic acid, bbp = 1,3-bis(benzoimidazol-2-yl)propane, H 2 bbop = 1,3-bis(benzimidazol-2-yl)-2-oxapropane), were synthesized and characterized by elemental analyses, IR spectra, single-crystal X-ray diffraction, and thermogravimetric analyses. Complex 1 has a 1D chain structure, while 2 has a 3-connected 2D network with (6 3 ) topology. Both structures are further connected by hydrogen bonds and π–π stacking interactions to form the 3D supramolecular architectures. DNA binding and catalytic properties of the two complexes were investigated.
