Abstract

(Ph₄As)₂[TcN(dto)₂] can be prepared starting from TcNCl₄^- or TcNCl₂(Ph₃P)₂. The compound crystallizes in at least two modifications: as well as a triclinic form (S. F. Colmanet and M. F. Mackay, Inorg. Chim. Acta, 147 (1988) 173) a monoclinic one has been found (space group C2/c, Z = 4, a = 19.424(3), b = 11.254(2), c = 24.958(3) Å, β = 107.68(1)°; R = 0.048). Distances and angles in the complex anions in both modifications are almost identical within experimental error. Oxidation of [TcN(dto)₂]^2- by Cl₂ produces the Tc(VI) complex TcNCl₄^- exclusively, whereas during the Br₂ oxidation technetium(VI) intermediates are generated containing mixed Br/dto coordination spheres which can be monitored easily by EPR spectroscopy.
