A range of new compounds such as N1,N4-bis(diphenylmethlene)benzene-l,4-diamine zirconium (IV) chloride [{(Ar)2NC6HsN(Ar)z}ZrCl4] (Ar = C6H5) complex counting the chelating amine and chloride in position tra... A range of new compounds such as N1,N4-bis(diphenylmethlene)benzene-l,4-diamine zirconium (IV) chloride [{(Ar)2NC6HsN(Ar)z}ZrCl4] (Ar = C6H5) complex counting the chelating amine and chloride in position trans have been prepared. Well-defined NI,N4-bis(diphenylmethlene)benzene-l,4-diamine zirconium (IV) chloride [{(Ar)2NC6H5N(Ar)2}ZrCl4] (Ar = C6H5) was obtained by stoichiometric addition of {(Ar)2NC6H5N(Ar)2} (Ar = C6H5) and {ZrC14} in ethanol at reflex temperature. IR, 1H NMR, electronic properties using hyperchem program study has been improved for this compound such as bond distance, and this compound was also defined as electric conductivity which proves to be useful for conductively compound. 展开更多
