A three-dimensional(3D) Keggin-type heteropolytungstate{Zn(phen)3}3[ZnW12O40]· 9H2O 1(phen=1,10-phenanthroline) has been synthesized through a conventional hydrothermal synthesis and was characterized by X-ray single-crystal diffraction analysis,X-ray powder diffraction(XRD),IR,UV-DRS,thermogravimetric analysis(TGA),thermal-dependent 2D-IR correlation spectroscopy(2D-COS IR) and Raman spectrum.Crystal data for compound 1:trigonal system,space group R3 with a=b=25.268(4),c=17.462(5) ?,γ=120o,V=9655(4) ?3 and Z=3.Compound 1 is allomorphic to {Co(phen)3}3[CoW12O40]·9H2O 2,which has been reported by Feng Chai et al.In compound 2,its prominent feature is that the decisive role of water molecules(O–H···O) builds a 3D supramolecular structure.However,in the structure of compound 1,the interlayer space is filled by Zn(phen)3]2+ cations which linked the layers via C–H···O hydrogen bonding interactions to construct a three-dimensional framework.Two compounds are different in weak interactions,so we identify them by Thermal-dependent 2D-COS IR.Moreover,the fluorescence of compound 1 was also described.
A three-dimensional (3D) Keggin-type heteropolytungstate {Zn (phen) 3} 3 [ZnW12O40] · 9H2O 1 (phen = 1,10-phenanthroline) has been synthesized through a conventional hydrothermal synthesis and was characterized by X- ray single -crystal diffraction analysis, X-ray powder diffraction (XRD), IR, UV-DRS, thermogravimetric analysis (TGA), thermal-dependent 2D-IR correlation spectroscopy (2D-COS IR) and Raman spectrum. Trigonal system, space group R3 with a = b = 25.268 (4), c = 17.462 (5) ?,? = 120o, V = 9655 (4)? 3 and Z = 3.Compound 1 is allomorphic to {Co ) 3} 3 [CoW12O40] · 9H2O 2, which has been reported by Feng Chai et al. In compound 2, its prominent feature is that the decisive role of water molecules (O-H · O) builds a 3D supramolecular structure .owever, in the structure of compound 1, the interlayer space is filled by Zn (phen) 3] 2+ cations which linked the layers via C-H ··· O hydrogen bonding interactions to construct a three-dimensional framework. Two compounds are different in weak in teractions, so we identify them by Thermal-dependent 2D-COS IR. Moreover, the fluorescence of compound 1 was also described.
