New water soluble complex [Zn(HPDDA)(2)(H2O)(2)(4,4'-Bipy)(2)] (n) (I), where H(2)PDDA is pyridazine- 4,5-dicarboxylic acid, 4,4'-Bipy = 4,4'-bipyridine), has been prepared by hydrothermal reaction and structurally characterized by X-ray single-crystal diffraction analysis (CIF file CCDC no. 835525 ) and elemental analysis. In I, each Zn2+ ion is six-coordinated by two oxygen atoms from the two HPDDA ligands, two nitrogen atoms from two 4,4'-Bipy and two oxygen atoms from two water molecules. The interactions of I with calf thymus DNA were studied by circular dichroism spectroscopy. The results indicated that this water soluble zinc complex show moderate binding with DNA and could be used for candidate for therapy of cancer.
