A novel polymer [Ni (H2O) 6 (Hdyma) 2] n [Hdyma = 2- (1,3-dithian-2-ylidene) malonic acid] was synthesized and characterized by elemental analysis and X-ray diffraction (Hdy-ma) 2] n belongs to the monoclinic system: the space group is P21 / n; the unit cell parameter a = 0.904 8 (2) nm, b = 0.514 03 (13) nm, c = 2.332 6 (6) nm, β = 99.755 (4) ° and V = 1.069 2 (5) nm3 with Z = 2 and Dc = 1.793 mg / = 13.66 cm-1, F (000) = 596, R1 = 0.0305, wR2 = 0.076 4. The central coordination number of Ni atoms is 6, and they coordinate with 6 water molecules respectively. Water and the two ligands Hdyma form a variety of hydrogen bonds between the formation of three-dimensional network of supramolecular coordination polymer.
