摘要：
Two transition-lanthanide metal-organic coordination polymers, {[CoLn(2)(Himdc)(2)(SO4)(2)(H2O)(4)]center dot H2O)(n) [Ln = Yb (1), Ho (2)] (H(3)imdc = imidazole-4, 5-dicarboxylic acid), have been synthesized by the hydrothermal reactions of lanthanide oxides, CoSO4 center dot 7H(2)O, H(3)imdc and H2O. Single-crystal X-ray diffraction analysis reveals that the isostructural complexes 1 and 2 possess unusual 2D wave-like heterometallic layers with 1D (Ln(2)O(2)O(3)O(2))(n) and [Ln(2)(SO4)(2)](n) inorganic chains constructed by the assembly of 1D left-/right-handed helical L-Ln(2)Co-L (L = Himdc) chains and SO42- anions, while a 3D framework is formed via hydrogen-bonding interactions interlayer.
