Popis: The reaction of copper nitrate Cu(NO3)2·3H2O with potassium salt of 1,1-cyclohexanediacetic acid (H2CHDAA) in an EtOH-toluene mixture affords the polymeric complex {[(EtOH)2Cu2(CHDAA)2]·EtOHn (1). The addition of pyridine to the Cu(NO3)2·3H2O-K2CHDAA reaction system in an EtOH-MeCN mixture results in the isolation of the unusual octadecanuclear heterometallic cluster [K2(η1-H2O)6(η1-py)8Cu16-(η1-OH)2(μ4-CHDAA)16]·EtOH·MeCN·3H2O (2). In complex 2, the hexadecanuclear metal carboxylate dianion (η1-H2O)6(η1-py)8Cu16(η1-OH)2(μ4-CHDAA)16 acts as the metal-containing macropolycyclic ligand. The newly synthesized compounds 1 and 2 were characterized by X-ray diffraction and EPR.
