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.

以两种新型非面式配位杂蝎形配体（heteroscorpionate ligands）——(4-羧基苯基)双(3,5-二甲基吡唑基)甲烷（L4c）与(3-羧基苯基)双(3,5-二甲基吡唑基)甲烷（L3c）——为配体构筑的铜(II)配合物，已完成合成并通过X射线衍射（X-ray diffraction）、电喷雾质谱（ESI-MS）、红外光谱（IR）、紫外-可见分光光度法（UV−vis spectroscopy）、电化学表征及磁化率（magnetic susceptibility）测试完成表征。本文探讨了将此类新型配合物作为构筑基元用于超分子架构构建的应用。
