N2  - The reaction of sodium 1,2-dicyanoethenedithiolate with [AsPh4][TcOCl4] in ethanol yields crystals of [AsPh4][ TcO ( mnt )2] (1). Crystals of (1) are monoclinic and belong to the space group P21/c with a 12.636(1), b 13.749(1), c 18.484(1)&#506;, &#946; 93.49(1)° with Z 4. Refinement on 3669 data measured with Cu K&#945; radiation converged at R 0.063. The structure consists of [ TcO ( mnt )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. The Tc =O bond distance is 1.655(6)&#506;.
