Interesting organic-inorganic copper-based nanostructures corresponding to [cation] + [C u n C l n + 1 ] −were successfully prepared by reacting chlorinate ionic liquids containing a coordinating center with CuCl. The value of “n”in anionic part [Cu n Cl n + 1 ] −was observed to be dependent on the properties of the cation in the used ionic liquids with which co-precipitation occurs. The ionic liquids containig functional groups such as N-sites or OH functions, which can form coordination and electrostatic interactions towards chlorocuprates(I), affect the coordination environment of copper species and the particle size in the gen- erated structures. All resulted microscopic data of [choline] + [C u C l 2 ] −, [N-benzyl DABCO] + [C u 4 C l 5 ] −, [N- benzyl nicotine] + [C u 4 C l 5 ] −and [choline] + [C u 3 C l 4 ] −showed the formation of nano-meter particles in the matrix of these materials. The new chlorocuprate(I) derived from choline chloride [choline] + [C u 3 C l 4 ] −was well characterized by elemental analysis, FESEM, TEM, ICP and mass spectrometry (MS) and was found to be efficient in the Sonogashira C –C cross-coupling reactions and the one-pot synthesis of quinazolin- 4(1H)-one derivatives via multicomponent reaction of isatoic anhydride, aldehyde and aromatic amines.
