摘要:
In the title complex, poly[aquacadmium-mu-bromo-mu-(3-pyridinecarboxylato-O,O':N)], [CdBr(C6H4NO2)-(H2O)](n), the Cd-II atom is six-coordinate. The carboxyI; late group of the nicotinate anion coordinates to the Cd-II atom as a chelate, with almost identical Cd-O distances [2.348 (3) and 2.331(3) Angstrom] and a small chelating angle of 56.0(1)degrees. Both the nicotinate and Br- anions bridge the Cd-II atoms to form polymeric di-catena chains in the crystal.
