Two mononuclear copper(II) complexes with pyrazole derivatives, 1,1'-(anthracen-9-ylmethylene)bis(1H-pyrazole) (L-1) and 9-(4-(di(1H-pyrazol-1-yl)methyl)phenyl)-9H-carbazole (L-2), of formulae [CuL1(CH3CN)(2)](ClO4)(2) (1) and [CuL2(CH3CN)(2)](ClO4)(2) (2) were prepared. Both complexes were confirmed by IR, MS, H-1 NMR, and elemental analyses. Complex 1 was also characterized by X-ray crystallography, confirming that copper(II) is coordinated by four nitrogen atoms from two L-1 and two oxygen atoms from two perchlorates. Furthermore, all ligands and complexes were tested in vitro for their antitumor activities using mouse melanoma cell line B16-F10, HepG2 human hepatoma cell line, and A549 human lung adenocarcinoma cell line. Both complexes displayed potent cytotoxicity and are promising substrates for further investigations.
