| Three benzil based, macrocyclic oxygen-, nitrogen-, and sulfur-containing ligands, (3,4,10,11 -tetraphenyl-1,2,5,6,8,9,12,13-octaazacyclotetradeca-7,14-dithione-2,4,9,11 -tetraene) ethanol (L 1), 10,1 l-diethoxy-3,4,10,11-tetraphenyl-1,2,5,6,8,9,12,13-octaazacyclotetradeca-7.14-dithione-2,4-diene (L2), (3,4,10,11 -tetraphenyl-1,2,5,6,8,9,12,13-octaazacyclotetradeca-7.14-dione-2,4,9,l 1-tetraene) ethanol (L3); a cyclic ligand, 6-ethoxy-l,6-diphenyl-4-oxo-3,4,5,6-tetrahydro-2,3,5-triazine (L5) and two open chain ligands, benzilsemicarbazone (L6) and benzilbisthiosemicarbazone (L4) are reported. These ligands react with copper(II) chlor ide, nitrate and acetate. The complexes obtained have been characterized on the basis o f N M R , IR, electronic and mass spectral studies, conductance and analytical data. The sto-ichiometry and the spectroscopic data o f the complexes indicate that the copper ions are coor dinated by neutral ligands or by ligand anions formed by loss o f protons from the ligand. The molecular and crystal structure o f 6-ethoxy-l,6-diphenyl-4-oxo-3,4,5,6-tetrahydro-2,3,5-triazine (L 5) was determined by X-ray diffraction; the space group is triclinic, P 1 with a = 7.865(1), b = 14.101(6), c = 15.733(9) A, a = 69.10(3)°, ß = 75.62(2)°, y = 86.69(2)°, V = 1578(1) A 3, Z = 4. | | | |
