Abstract
Three new mononuclear complexes CdLClO42·4MeCN 1 L = 5111723tetratbutyl25262728tetrakispiperidinocarbonylmethoxycalix4arene ZnLClO42·4MeCN·CH2Cl2 2 CuLClO42·3MeCN·Et2O 3 have been synthesized and characterized by elemental analysis and Xray single crystal diffraction CCDC 838342 838343 and 838344 The results of the crystal structural analyses show that calix4arene backbones in 1 2 3 are fixed in the cone conformation while the divalent metal cations Cd Zn and Cu are coordinated with the discrepant geometry The cadmium ion in 1 is eightcoordinated with four carbonyl oxygen atoms and four ethereal oxygen atoms in the low rim of calix4arene whereas zinc ion in 2 and copper ion in 1 are fourcoordinated with the acyl oxygen atoms The atomic net charges distribution and frontier molecular orbital energies were obtained by Gaussian 98 program with DFT method at B3LYP/lanl2dz level Furthermore the SODlike activities of 3 were measured by xanthine/xanthine oxidaseNBT assay at pH 72 and 78This work was financially supported by the Doctoral Startup Foundation of Anhui Normal University the Natural Science Foundation of Anhui province No 090416234 and the National Natural Science Foundation of China No 20901002 20872001 and the Program for the NCET NCET100004
