Two novel polymeric complexes, [Gd(H5TCAS)(H2O)7]·4H2O 1 and [Gd(H5TCAS) (CH3COCH3)(H2O)6]·6H2O 2 (H4TCAS = p-sulfonatothiacalix[4]arene), have been synthesized and characterized by single-crystal X-ray diffraction analyses. Complex 1 crystallizes in monoclinic, space group C2/m with a = 20.2308(12), b = 19.0894(10), c = 12.2448(7) , β = 101.847(3)°, V = 4628.1(5) 3, C24H43GdO27S8, Mr = 1169.25, Z = 4, Dc = 1.690 g/cm3, F(000) = 2380, μ = 1.879 mm-1, the final R = 0.0404 and wR = 0.1038 for 5127 observed reflections with I > 2σ(I). Complex 2 is pseudo-isostructural with complex 1.
