Rezumat

The interaction of Cu(BF4)2 with 2,2′-dithiodibenzoic acid (H2dtdb) in a CH3OH/dmf mixture leads to the formation of extended polymeric solids {[Cu(tdb)(dmf)]·(dmf)}n (1) and {[Cu2(tdb)(sdb)(dmf)(H2O)]·2(dmf)}n (2), where tdb2− = 2,2′-thiodibenzoate, sdb2− = 2,2′-sulfinatodibenzoate, dmf = N,N′-dimethylformamide. In all of the cases, reactions proceed with extrusion of one S atom and in 2 with additional S oxidation. Compound 1 represents 1D coordination polymer, while 2 exhibits 2D structure. Both compounds are built from similar [Cu22-RCOO)4] metal clusters with the Cu(II) atom in the O5 square-pyramidal geometry. All new solids were characterized by IR spectroscopy, thermogravimetric and single crystal X-ray diffraction analyses.
