Abstract
The new complex alpha-H6P2W18O62middot 6phen middot 10H2O, consisting of the heteropolytungstophosphate α-H6P2W18 O62middotxH2O and organic substrate 1,10-phenanthroline (phen) has been synthesized and spectroscopically characterized. There appears to be a sizeable electron-transfer interaction between the electron-rich aromatic organic moiety and the inorganic acid, both in the solid state and in solution, and this interaction is thought to be responsible for the formation of the title compound, which exhibits second-order and third-order nonlinear optical responses of Isample2 omega=0.6IKDP2 omega and χ(3)=3.35*10-11esu, respectively.
