Tridentate and bidentate copper complexes of [2.2]paracyclophanyl-substituted thiosemicarbazones, thiocarbazones, hydrazones and thioureas

New paracyclophane-substituted thiosemicarbazones, thiocarbazones, hydrazones and thioureas were synthesized in order to study their complexation capability towards copper (I) and Cu (II) salts. Twelve of Cu complexes were characterized by ESI, IR and NMR spectra in addition to elemental analyses. Tridentate and bidentate of the aforesaid paracyclophane-substituted ligands were observed. Thiosemicarbazonyl, hydrazonyl and thiourea paracyclophane derivatives formed with Cu(I) and Cu(II) salts tridentate and bidentate structures, whereas no complexes were observed for the prepared thiocarbazone derivatives.
