Twocobaltcoordinationpolymers [CoII2(ida)2(H2O)2]n (1) and [Na2CoIII2(ida)4(H2O)4]n·2nH2O (2) (H2ida = iminodiacetic acid) have been synthesized and characterized by single-crystal X-ray diffraction analysis. Compound 1 exhibits a two-dimensional framework, in which twocobalt atoms exhibit different coordination environments: one is equatorially coordinated by twoidaligands, while another is
