| Abstract: | A Dawson structured heteropolycompound (C_5H_6N)_(4.5)H_(1.5)(P_2W_(18)O_(62))·1.5H_2Owas hydrothermally synthesized and characterized by IR and single-crystal X-ray diffraction.The X-ray crystallography indicates that the title compound crystallizes in monoclinic lattice,C2/m space group,with a = 2.6970(3) nm,b = 1.39730(16) nm,c = 2.0777(2) nm,β = 102.33(0)°,V = 7.64927(364) nm3,Z = 4,R = 0.0412,wR2= 0.1016.The anions of the title compound display an infinitely extended one-dimensional chain by the connectivity of protonated pyridine molecules for hydrogen bonding interaction. |
