Answer:
Synthesis, Characterization, and Magnetic Properties of a Series of Copper(II) Chloride Complexes of Pyridyliminebenzoic Acids.
Explanation:
A series of Cu(II) halide complexes, Сu(HL1)Cl2∙CH3OH (1), [Сu(L1)Cl]2∙H2O (2), [Сu(HL2)Cl2]2∙2DMF (3), [Cu(HL2)2Cl]nCln·2nH2O (4) and [Cu(L3)Cl]n (5), containing pyridyliminebenzoic acids HL1, HL2 and HL3 derived from o-, m- and p-aminobenzoic acids, respectively, have been obtained as single crystals and characterized by elemental analysis, IR, EPR spectroscopy, magnetic measurements and single-crystal X-ray diffraction techniques. The results obtained show the formation of molecular (1), dimeric (2, 3) and polymeric structures (4, 5) based on chloride (1-4) and carboxylate bridges (5) with copper(II) atoms in the square-pyramidal geometry of varying degrees of distortion.
