Heteroligand Co(II) and Cu(II) Complexes with 3,3-Bis(3,5-dimethylpyrazol-1-yl)-1-phenylpropan-1-one: Synthesis and Crystal Structure

The reaction of 3,3-bis(3,5-dimethylpyrazol-1-yl)-1-phenylpropan-1-one (L) with cobalt(II) chloride and copper(II) chloride yielded neutral, isostructural heteroligand complexes [LMCl2] with M = Co for I and M = Cu for II. Their structures were determined by direct X-ray diffraction methods (CCDC nos. 2478389 for I, 2478390 for II). In both complexes, the metal center has a tetrahedral coordination environment, and L coordinates to the metal ion in a bidentate manner.
