A series of linear coordination polymers, metallacycles of cadmium(ii) and mercury(ii) of flexible carboxylic acid ligands, RCH{3-CH3-,5-CH 3-,6-(-OCH2CO2H)C6H 2}2, (when R = C6H5, (H 2L1); 2-NO2C6H4- (H 2L2) and 3-NO2C6H4- (H2L3)) are synthesized and characterized. [CdL 1 (py)3]n·3nH2O (py = pyridine) is a linear coordination polymer, whereas [CdL2(py)(CH 3OH)]2·CH3OH is a dinuclear complex of cadmium with a Cd2O2 type of core. The latter is obtained from reaction of cadmium(ii) acetate with H2L2 in methanol followed by reaction with pyridine. A similar reaction of cadmium(ii) acetate with H2L2 in dimethylformamide results in the formation of a cadmium metallacycle, namely [CdL2 (py)2(H 2O)]2·H2O. The H2L 3 reacted with cadmium(ii) acetate in the presence of pyridine to form a metallacycle [CdL3(py)2(H2O)] 2·3H2O. The ligand H2L2 form mercury(ii) metallacycle [HgL2(4-mepy)2]2 in the presence of 4-methylpyridine (4-mepy) and the ligand H2L 3 forms metallacycle [HgL3(3-mepy)2] 2·DMF in the presence of 3-methylpyridine (3-mepy). The potassium salts of H2L1 and H2L2 were found to be coordination polymers and these potassium coordination polymers were structurally characterized.
