New tri- and tetranuclear macrocyclic silver(I) and copper(I) 3-ferrocenyl-5-(trifluoromethyl)pyrazolates were prepared: [{(3-((η"5-C_5H_4)Fe(η"5-C_5H_5))-5-(CF_3)-Pz}M]{sub 3} (M = Cu (1), Ag (2)) and [{(3-(( η"5-C_5H_4)Fe(η"5-C_5H_5))-5-(CF_3)-Pz}Cu]{sub 4} (3). The structures of compounds were established by X-ray diffraction analysis. In the crystalline state, a planar trinuclear silver-containing macrocycliс pyrazolate and a saddle-shaped tetranuclear copper-containing macrocycle are formed. The introduction of a bulky substituent, ferrocene, into the pyrazole ligand results in complete shielding of the acidic metal sites, which precludes the coordination of base molecules.
