AB  - Three condensation products of usnic acid with the hydrazides of alpha-naphthoic, caprylic, and oxamic acids, respectively, have been prepared and characterized by spectrometric methods. A reassignment of the C-13-NMR spectral data of usnic acid has been done. The crystal structure of usnic acid 11-[(1-naphthoyl)hydrazone] ethanol solvate (1:1) has been determined. This substance crystallizes in the monoclinic crystal system, the space group P2(1), with the unit cell dimensiones a=7.7365(7) Angstrom, b = 19.632(2) Angstrom, c = 9.4150(15) Angstrom, beta = 108.830(11)degrees, V = 1405.0(4) Angstrom(3), and Z=2. At the end of the structure analysis R = 0.055, R-w = 0.052 and S = 0.89. The antibacterial activities of the compounds have been evaluated. The greatest activity against Staphylococcus aureus was found for usnic acid, somewhat lower for the derivatives with hydrazides of alpha-naphthoic and caprylic acid, and much lower for the derivative with semioxamazide. The activities of these compounds probably depend on their lipophilicity.

AB  - The complexes of Cu(II) and condensation products of usnic acid with the acyl hydrazides of alpha-naphthoic, caprylic and oxamic acid, as well as the-derivative of usnic acid with thiosemicarbazide have been synthesized and characterized by elemental analyses, molar conductivity, magnetic moment measurements and IR spectroscopy. It was found that the derivatives act as tridentates occupying three coordination places in the square planar molecules with the fourth coordination site occupied by a solvent molecule. The complexes were tested for in vitro growth inhibitory activity against the bacterial species Escherichia coli and Staphylococcus aureus. The complexes have higher antibacterial activities compared to both the usnic acid derivatives and Cu(II) ions.

AB  - This paper reports the first Co(II) complexes with a singly-and doubly-deprotonated H2L ligand (H2L = 2',2'''-(2,6-pyridindiyldiethylidene)dioxamohydrazide belonging to the planar pentadentate class. The complexes were characterized by elemental analysis, thermal analysis, IR spectroscopy, molar conductivity and magnetic susceptibility measurements. The crystal structure of [Co(L)(H2O)(2)].6H(2)O complex has been determined. The pentagonal bipyramidal geometry present in the previously synthesized complex [Co(H2L)(H2O)(MeOH)](ClO4)2(,) wherein the ligand is present in a neutral form, has been preserved around Co(II).
