The crystal contains two independent [Cu(L-Ile)(TATP)(H2O)]+ complexes for Cu1 and Cu2, respectively, having essentially the same distorted square-pyramidal structure, where each Cu ion is coordinated with two nitrogen atoms of TATP and the amino nitrogen atom and one carboxylate oxygen atom of L-Ile in the equatorial positions and one water oxygen atom at an axial position. Furthermore, the primary studies on the interaction between the complex and calf thymus DNA were also performed by electronic absorption spectroscopy and viscosity methods. CCDC: 244231.展开更多

The complex was crystallized in the triclinic space group P1, with two independent molecules in a unit cell. Two Cu(Ⅱ) ions in each complex [Cu2(TATP)2(L-Leu)2(CIO4)2] molecule were found to be in different coordination geometries, i.e., Cu2 or Cu4 of a distorted square-pyramidal geometry coordinated with two nitrogens of TATP, the amino nitrogen and one carboxylate oxygen of L-Leu and one oxygen of perchlorate, and Cul or Cu3 with an octahedral geometry coordinated with the above stated similar coordinated atoms, and another carboxylate oxygen of L-Leu coordinating to Cu2 or Cu4. The complex can interact with CT-DNA by an intercalative mode and cleave pBR322 DNA in the presence of ascorbate.展开更多
