Abstract

A two-dimensional layer compound of mono-vacant Keggin polyanion,Na3H8[La(PW11O39)2]·19H_2O was synthesized and characterized via IR and single crystal X-ray diffraction analysis.Crystal data are as follows: monoclinic,P2/n space group,a=1.343 43(8) nm,b=1.259 35(7) nm,c=3.541 8(2) nm,β=99.151 0(10)°,V=5.915 9(6) nm3,Z=2,R1=0.042 9,wR2=0.119 4.The heteropolyanion [La(PW11O39)2]11-clusters are linked through NaO4 units to form one-dimensional chains,and the chains are linked through NaO6 units to form two-dimensional layers.
