摘要：

The first ditungsten(II,II) complexes with amine ligands of the formula W2Cl4 (NH2R)(4) (R=Pr-n (1), Bu-t (2), Cy (3)) have been prepared by reduction of a tungsten(IV) compound with potassium graphite in the presence of the appropriate amine. The X-ray crystal structure determination of 3 revealed a quadruply-bonded ditungsten molecule-having D-2d geometry and a trans arrangement of the amine Ligands on each metal atom.
