A new 3‐D inorganic‐organic hybrid compound {[Cu(4,4′‐bipy)] 3 (4,4′‐bipy)}[PMo 12 O 40 ]·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) Å, α = 113.3560(10)°, β = 93.8730(10)°, γ = 99.0300(10)°. V = 1579.4(3) Å 3 , Z = 1. Structural analysis indicates that compound 1 exhibits a three‐dimensional structure, in which Keggin anions [PMo 12 O 40 ] 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 [PMo 12 O 40 ] 3− and [Cu(4,4′‐bipy)] + n chains.
