Synthesis and characterization of copper(II) complexes of nonfacially coordinating heteroscorpionate ligands (4-carboxyphenyl)bis(3,5-dimethylpyrazolyl)methane and (3-carboxyphenyl)bis(3,5-dimethylpyrazolyl)methane.
Complexes of Cu(II) derived from two new nonfacially coordinating heteroscorpionate ligands, (4-carboxyphenyl)bis(3,5-dimethylpyrazolyl)methane (L4c) and (3-carboxyphenyl)bis(3,5-dimethylpyrazolyl)methane (L3c), have been synthesized and characterized by X-ray diffraction, ESI-MS, IR, and UV-vis spectroscopy, electrochemistry, and magnetic susceptibility. The use of these new complexes as building blocks for the construction of supramolecular architectures is discussed.
