A new 3-D inorganic-organic hybrid compound {[Cu(4,4'-bipy)](3)(4,4'-bipy) [PMo12O40]center dot 2H(2)O (1) was hydrothermally synthesized and characterized by IR, TG and X-ray diffraction analysis. Single crystal X-ray diffraction confirms that this compound crystallizes in the triclinic crystal system, space group P-1 with a = 10.9180(11), b 12.3759(13), c = 13.0264(13)angstrom, alpha = 113.3560(10)degrees, beta = 93.8730(10)degrees, gamma = 99.0300(10)degrees. V 1579.4(3) angstrom(3), Z = 1. Structural analysis indicates that compound 1 exhibits a three-dimensional structure, in which Keggin anions [PMo12O40](3-) are linked by infinite [Cu(4,4'-bipy)](+)(n) chains through Cu-O, and come into being a 3-D inorganic-organic hybrid open framework. The guest 4,4'-bipy molecules and water molecules are filled in the channel formed by Keggin anions [PMo12O40](3-) and [Cu(4,4'-bipy)](+)(n) chains.
