摘要
A polyoxovanadium borate [Na（H2O）]2[Na（H2O）2]2[Cu（en）2][V12B18O54（OH）6]·（H3O）2·（H2O）18 1（en = ethylenediamine） has been hydrothermally synthesized and characterized by IR,two-dimensional infrared（2D IR） correlation spectroscopy with magnetic and thermal perturba-tion,thermal IR spectroscopy,thermal gravimetric analysis and single-crystal X-ray diffraction.It crystallizes in triclinic,space group P with a = 12.981（3）,b = 13.044（3）,c = 14.208（3） ,α = 63.98（3）,β = 77.17（3）,γ = 14.208（3）°,V = 2001.0（8） 3,Z = 1,Mr = 2518.05,Dc = 2.090 g/cm-1,F（000） = 1255.0,Mu（mm-1） = 1.756,λ（MoKα） = 0.71073 ,R = 0.0625 and wR = 0.1952.In 1,the [V12B18O54（OH）6]8- units are connected by [Cu（en）2]2＋,binuclear Na（1） and Na（2） to form a three-dimensional porous framework.
