Abstract
- Abstract: Two Keggin-based inorganic–organic hybrid complexes, [Co2(H2O)2(btb)4(HPMoVI 10MoV 2O40)] (1) and [Co2(btx)5(HPMoVI 10MoV 2O40)] (2) (btb=1,4-bis(1,2,4-triazol-1-yl)butane, btx=1,6-bis(1,2,4-triazol-1-yl)hexane), have been synthesized under hydrothermal conditions and characterized by single-crystal X-ray diffraction, elemental analyses, IR spectra, and thermogravimetric analyses (TGA). Complex 1 exhibits 2D ladder-like metal–organic layers, which are further linked by the Keggin anions to construct a 3D twofold interpenetrating framework. Complex 2 shows a 2D metal–organic network containing two kinds of pores, in which the Keggin anions acting as bidentate inorganic linkages reside alternately. The flexible bis(triazole) ligands btb and btx with different spacer lengths play an important role in the formation of the final structures. In addition, the electrochemical and photocatalytic properties of 1 and 2 have been reported. [Copyright &y& Elsevier]
