One novel compound, [Cu(3-OHpy)4F2] (complex 1), was synthesized from copper(II) tetrafluoroborate and 3-OHpy (3-hydroxypyridine) and characterized. In addition, several other compounds were resynthesized using a molecular self-assembly approach from copper(II) complexes and 3-OHpy. The novel compound, [Cu(3-OHpy)4F2] (1), was characterized by X-ray crystallography. Using infrared and electronic spectroscopy initial characterization was done on complex 1 as well as on the resynthesized compounds for which the structure had already been solved. Complex 1 consists of a copper(II) atom in a octahedral environment bound to four 3-OHpy ligands and two fluoride atoms in the axial positions. Particularly interesting was the elongation of the F-Cu-F axis to 2.3535 A. Complexes 2 [Cu3(3-OHpy)6(3-Opy)2(H20)2(S04)2-4H20]n, and 3 [Cu(3-OHpy)3(H20)(S04)H20]n, were synthesized from copper(II) sulfate and 3-OHpy in a single test-tube layering experiment and were hypothesized to form as a result of a ligand concentration gradient. In a similar fashion, complexes 4 [Cu2(3-Opy)4(H20)2(OAc)2]n, and 5 [Cu(3-OHpy)2(OAc)2]n were formed as a result of a ligand concentration gradient in a single test-tube reaction from copper(II) acetate and 3-OHpy. Complexes 6-8 were synthesized from copper(II) X and 3-OHpy (X = nitrate, bromide, and chloride, respectively) and showed high similarity from IR and electronic analysis. X-ray data could not be obtained for these compounds because they did not form single crystals through the methods employed.
