The title compound [Cu(HSSA)(py)3H2O]n (H3SSA = 5-sulfosalicylic acid,py = pyridine) Ⅰ has been synthesized and structurally determined by single-crystal X-ray diffraction. Ⅰ was further characterized by elemental analyses,thermogravimetric analyses,IR and UV-visible spectroscopy. The crystal belongs to the monoclinic system,space group P21/c with a = 9.4564(10),b = 18.2679(19),c = 15.7284(12) ,β = 126.045(4)o,V = 2196.9(4) 3,Z = 4,Dc = 1.618 g/cm3,Mr = 535.02,μ = 1.141 mm-1,F(000) = 1100,λ(MoKα) = 0.71073 ,the final R = 0.0429 and wR = 0.1044 for all observed reflections. In the structure,every two Cu(Ⅱ) atoms are bridged by a bivalent 5-sulfosalicylic anion to form a 1D chain-like coordination polymer. Lattice waters between chains link them to form 2D layers which are further linked by C-H···O hydrogen bonds to form a three-dimensional supramolecular network.
