| synthesis method : [Cu(phen)H2O]2[CrH5Mo6O24]·4H2O 1 ,K[Co(phen)2]2[BW12O40]·2H2O 2 , Cu(en)2[H4W12O42][H2en]3[en]·6H2O 3. The structures of the three compounds were determined by single crystal X-ray diffraction, and the influencing factors of the structures were studied. Compound 13 are characterized by elemental analysis, UV-vis, IR, and TG-DTA. Compound 1 and 2 exhibit strong fluorescent emission and may be applied for potential photoactive material.Compound 1 has been hydrothermal synthesized and structurally characterized. Compound 1 crystallizes in the triclinic space group P-1 with a = 8.3856(5) , b = 9.2366(5) , c = 14.7623(8) ,α= 87.6400(10) ,β= 74.4400(10) ,γ= 72.4270(10) , V = 1049.11(10) 3, Z = 1 and GOF = 1.112. Additionally, the IR, TG-DTA and Signal-crystal X-ray analysis of compound 1 were studied. We also studied the electrochemical properties, electrocatalytic properties and the fluorescence of 1. Compound 2 has been hydrothermally synthesized and structurally characterized.Compound 2 crystallizes in the triclinic, space group P-1 with a = 10.8680(7) , b = 13.3219 (8) , c = 13.5855 (8) ,α= 69.5090 (10) ,β= 71.6080 (10) ,γ= 78.4050 (10) , V = 1739.28 (18) 3, Z = 13 and GOF = 1.142. X-ray diffraction analysis reveals that compound 1 is constructed from [BW12O40]5- clusters coordinated to Co(II)-phen units and water molecules, which are further in close contact forming three-dimensional micropore frameworks via hydrogen bonds. Additionally, fluorescent of compound 2 are studied.compound 3 has been hydrothermally synthesized and structurally characterized. Compound 3 crystallizes in the monoclinic, space group P 2(1)/n with a = 11.8481 (9) , b = 11.7394 (9) , c = 20.5935 (16) ,α= 90.00 ,β= 99.2110 (10) ,γ= 90.00 , V = 2827.44 3, Z = 21 and GOF = 0.982. X-ray diffraction analysis reveals that compound 1 is constructed from polyoxometalates clusters coordinated to chainlike structure. |
