An interesting 3d-4f complex [CeCo(HIDA)(IDA)(2)] (n) (I) (IDA = iminodiacetic acid) was synthesized under hydrothermal conditions and characterized by IR, TG, and single-crystal X-ray diffraction analysis. Complex I crystallizes in the monoclinic system, space group C2/c with a = 9.7033(19), b = 24.141(5), c = 8.5810(17) , beta = 115.01(3)A degrees, V = 1821.6(6) (3), Z = 4, rho (c) = 2.152 g/cm(3), F(000) = 1148. Crystallographic data for I were collected at 293 K with a Rigaku R-axis Rapid IP diffractometer using graphite monochromatic MoK (alpha) radiation (lambda = 0.71073 ) and IP technique, GOOF = 0.994, the final R = 0.0245 and wR = 0.0763 (I > 2 sigma(I)). Complex I is a two-dimensional layer structure, in which the Ce(III) center is surrounded by ten oxygen atoms from different IDA ligands. The Co(II) center is six-coordinated by four oxygen atoms and two nitrogen atoms from two different IDA ligands. The carboxylic oxygen atom connected such units along the z axis to form a one-dimensional chain-like structure. The IDA ligand connects neighboring chains to form a two-dimensional layer structure.
