摘要
The isostructural compounds [PPh4][(CPM(mu(2)-Se-2))(3)(mu(3)-O)(mu(3)-TeSe3)] (M = Zr, Hf) have been synthesized by the reactions of Na-2[TeSe3] with CP2MCl2 in NN-dimethylformamide (DMF). The structure of the anion comprises a triangle of MCp groups bridged by mu(2)-Se-2 groups and capped by a mu(3)-TeSe3 and a mu(3)-O group. These compounds represent the first examples of the mu(3)-TeSe32- ligand capping a metal system. (c) 2005 Academie des sciences. Published by Elsevier SAS. All rights reserved.
