Abstract

Abstract : Two Cu coordination polymers [Cu(bpmt)Cl2 · 2DMF] n (1 ), [Cu(bpmt)( μ ‐Cl)· DMSO] n (2 ) [bpmt = N 1, N 4 ‐bis(pyridin‐2‐ylmethyl)terephthalamide)], were synthesized and characterized. X‐ray single‐crystal diffractions revealed complex 1 exhibits a one‐dimensional (1D) chain in which central Cu II ions are located in a six‐coordinate slightly distorted octahedral structure. Complex 2 features 1D chain composed of Cu I –Cl bridges and all the central Cu I ions are situated a twisted tetrahedral configurations. Multi‐spectroscopic DNA interaction studies indicate that the two complexes may bind to DNA via groove binding modes, and the calculated binding constants are 1.42 × 10 4 (1 ‐CT‐DNA) and 1.41 × 10 4 (2 ‐CT‐DNA). Both complexes are also capable of efficiently cleaving plasmid pBR322 DNA in the presence of H2 O2 via an oxidative mechanism. Furthermore, 1 and 2 are employed as catalysts for the oxidation of 1‐phenylethanol to acetophenone. Complex 1 displays good catalytic potential with the conversion rate reaches 99 % using tert ‐butyl hydroperoxide (TBHP) as oxidant and CH3 CN as solvent at 60 °C for 2.0 h. Abstract :
