%X The reaction of sodium 1,2-dicyanoethenedithiolate [( mnt )Na2] with (NH4)2 [TcBr6] in ethanol yields crystals of (AsPh4)2 [ Tc ( mnt )3] (1) after precipitation with AsPh4Cl. The crystal structure of (1) has been determined by X-ray diffraction. Crystals are orthorhombic, space group Pbcn , a 20.256(1), b 15.513(1), c 18.274(1)&#506;, Z 4. Refinement on 2910 diffractometer data measured with Cu K&#945; radiation converged at R 0.056. The structure consists of [ Tc ( mnt )3]2- anions and (AsPh4)+ cations . The technetium(IV) atom is coordinated to six sulfur atoms to give a distorted octahedron.
