Crystal Structure of the Polymer Copper(II) Complex with 1-Phenyl-3-Methyl-4-Formyl-5-Hydroxypyrazole Hetarylhydrazone

This is the authors' abstract. We don't add key points for this paper.

A new coordination polymer of Cu(II) based on 1-phenyl-3-methyl-4-formyl-5-hydroxypyrazole 4,6-dimethylpyrimidylhydrazone is synthesized. The polymer is studied by X-ray diffraction analysis (CIF file CCDC no. 1565772). It is shown that the polymer is formed due to the coordination of the nitrogen atom of the pyrazolone fragment to the copper(II) ion of the adjacent monomeric fragment.
