An unusual cerium-containing decaoxotungstate complex, (NH4)(3)[Na-5(H2O)(17)Cl]{[Na(H2O)(4)](2)[CeW10O36]} center dot 6H(2)O (1) has been synthesized and characterized by IR, TG, and single crystal X-ray diffraction studies (yellow crystals, orthorhombic, space group Imm2, a = 11.473(2), b = 15.225(3), c = 17.646(7) angstrom, V = 3082.3(15) angstrom(3), Z = 2, R = 0.046). In this compound, sandwichtype [CeW10O36](9-) clusters are linked by binuclear [Na-2(H2O)(8)](2+) units by sharing oxygen atoms into linear chains, which are further extended into a 2D supramolecular network via pentanuclear [Na-5(H2O)(17) Cl](4+) units by strong hydrogen bonding interactions.
