A new compound, [Cu{sup I}(H{sub 2}O)(Hbpp){sub 2}] Subset-Of {l_brace}[Cu{sup I}(bpp)]{sub 2}[PW{sub 11}Cu{sup II}O{sub 39}]{r_brace} (1) (bpp=1,3-bis(4-pyridyl)propane), has been hydrothermally synthesized and structurally characterized by single crystal X-ray diffraction. In compound 1, the unusual -A-B-A-B- array mono-substituted Keggin anion-chains and 24-membered (Cubpp){sub 2} cation-macrocycles are linked together to form a (2, 4) connected 3D framework with channels of ca. 9.784 Multiplication-Sign 7.771 A{sup 2} along two directions, in which the [Cu(H{sub 2}O)(Hbpp){sub 2}] coordination fragments as guest components are trapped. The photocatalytic experiments of compound 1 were performed, which show a good catalytic activity of compound 1 for photodegradation of RhB. Furthermore, the IR, TGA and electrochemical properties of compound 1 were investigated. - Graphical abstract: An unusual example of mono-substituted Keggin anion-chain based hybrid compound that possesses a 3D structure has been synthesized, which offers a feasible route for synthesis of such compounds. Highlights: Black-Right-Pointing-Pointer The first example of -A-B-A-B- array mono-substituted Keggin chain is observed. Black-Right-Pointing-Pointer An unusual three dimensional structure based mono-substituted Keggin anion-chains. Black-Right-Pointing-Pointer The photocatalysis and electrochemical properties of the title compound were studied.
