“…4b), this band shifts to 496 nm, a fact that could be due to EtOH(solvent)-interactions (which replace the -* interactions between neighboring rings in the solid). It is interesting that in ethanolic solutions, the band of IV in the visible shifts to 490 nm, which has been attributed to the À O2-C10¼C9-C8¼O3$O2¼C10-C9¼C8-O3 À mesomerism (p-quinone $ o-quinone) [26]. Actually, what really seems to happen is that protonation of O2 fixes the first form while deprotonation gives place to the mesomerism between the two forms.…”

The reaction of lapachol, 2-hydroxy-3-(3-methyl-2-butenyl)-1,4-naphtoquinone, C 15 H 14 O 3 , with zinc acetate, in ethanol, produces a chelate formula Zn(C 15 H 13 O 3 ) 2 (C 2 H 6 O) 2 , whose structure has been determined by single crystal X-ray diffraction. It pertains to the triclinic system, space group P " 1 1 (No. 2), a ¼ 8.2380(3) A ˚, b ¼ 9.4900(2) A ˚, c ¼ 11.0110(4) A ˚, ¼ 112.536(2) , ¼ 91.204(2) , ¼ 92.664(2) , Z ¼ 1. Some spectroscopic and chemical properties of the complex are also reported.
