%X The reaction of benzene-1,2-dithiol (bdtH2) with [AsPh4] [TcOCl4] in aqueous alcohol yields crystals of [AsPh4] [ TcO ( bdt )2] (1) from acetonitrilelethanol. The crystal structure of (1) has been determined by X-ray diffraction and found to be isostructural with [PPh4] [ MoO ( bdt )2]. Crystals art monoclinic and belong to the space group Cc with a 12.652(1), b 15.783(1), c 16.622(1) Å, &#946; 93.03(1)º with Z 4. Refinement on 2828 diffractometer data measured with Cu Ka radiation converged at R 0.030. The structure consists of [ TcO ( bdt )2]- anions and [AsPh4]+ cations. The technetium(V) atom is five-coordinate, with the four sulfur atoms in the basal positions and the oxo ligand in the apical position, to give a distorted square-pyramidal environment about the technetium.
