Data from: Evaluating Coordinative Binding Mechanisms through Experimental and Computational Studies of Methoxy-substituted Arylazothioformamide Copper(I) Complexes

UV-Vis spectroscopic titration studies of ATF ligands 6, 8 and 10 with Cu salts were prepared as follows: ligand solutions were prepared to 1.45 x 10-4 M in acetonitrile. 1.2 mL of ATF solution was added to a quartz cuvette. Titrations were performed with Cu halide salts and [N(Bu4)2(µ-I)-Cu2I4] utilizing 1.35 mM stock solutions in acetonitrile and sequentially adding 13 µL (roughly 0.1 equivalent of metal salt) until reaching a metal salt concentration of three equivalents (a final volume of 2.0 mL); [(CH3CN)4CuI]BF4 salts titrations were performed in the same manner as above to a final 1.5 equivalents. Each titration was performed in triplicate.
