摘要：

The arsenic-functionalized zirconocene arsenide complexes [Cp'Zr-2{As(SiMe(3))(2)}(Cl)] (1; Cp' = C(5)H(4)Me) and [Cp(2)Zr{As(SiMe(3))(2)}(2)] (2; Cp = C5H5) are obtained by the reaction of [Cp'2ZrCl2] or [Cp(2)ZrCl(2)] with Li(THF)(2)As(SiMe(3))(2). 1 and 2 were characterized by spectroscopy (IR, NMR, mass spectrum) and by X-ray structure determinations. determinations. In 2 there are two distinctly different As(SiMe(3))(2) groups and Zr-As bond lengths (Zr-As1 = 2.799(2) Angstrom, Zr-As2 = 2.616(2) Angstrom A), indicating the presence of a Zr-As1 single bond and a Zr-As2 double bond.
