Four new 3d-4f heterometallic coordination polymers [Cu(3)Eu(2)(2,5-pydc)(6)(H(2)O)(12)]center dot 4(H(2)O) (1), [Zn(2)Eu(2)(2,5-pydc)(5)(H(2)O)(2)]center dot 3(H(2)O) (2), and [Co(3)Ln(2)(2,6-pydc)(6)(H(2)O)(6)]center dot 4(H(2)O) (Ln = Eu, 3; Dy, 4) (H(2)pydc = pyridinedicarboxylic acid) have been synthesized and characterized. All of these compounds have extended 3D coordination frameworks containing supramolecular 1D channels, in which lattice water molecules are located. Hydrogen bonds stabilize the 3D frameworks. Additionally, a study of their fluorescence properties has indicated that compounds 1 and 2 show the characteristic transitions of Eu(3+). Weak antiferromagnetic interactions are observed in compound 3.
