Abstract:
The unique palladium(II) complexes, namely, (Phen)Pd((CF3)2pz)2, (Phen)Pd(MeCF3pz)2, and [(Phen)Pd2(μ-dmpz)2(dmpz)(Hdmpz)](OAc)2H, where (CF3)2pzH is 3,5-bis(trifluoromethyl)pyrazole, MeCF3pzH is 3-methyl-5-trifluoromethylpyrazole, Hdmpz is 3,5-dimethyl-pyrazole, Phen is 1,10-phenanthroline, have been obtained by the reactions of (Phen)Pd(OAc)2 with the corresponding free NH-pyrazoles. According to the X-ray data, in the mononuclear pyrazolate complexes the PdII atom has a square planar environment of nitrogen atoms of phenanthroline and two monodentate-bound pyrazolate anions. The binuclear pyrazolate-bridged complex is additionally stabilized by intramolecular hydrogen bonding of the terminal dmpz anion and Hdmpz.
