Abstract (Bu 4 N) 2 [TcN(dmit) 2 ] (dmit 2− = isotrithionedithiolate) was prepared from Na 2 dmit, (Bu 4 N)[TcNCl 4 ] and (Bu 4 N)Cl in acetonitrile. The compound crystallises in the monoclinic space group C2/c with a unit cell of the dimensions a = 23.143(5), b = 8.342(2), c = 26.382(5) Å, β = 95.12(3), Z = 4. The TcN bond distance is comparatively short at 1.615(6) Å. Tc and N(1) are situated on a two‐fold crystallographic axis. The general coordination geometry is a square pyramid with the four sulfur atoms forming the basal plane and the nitrido nitrogen at the apex. The technetium is located 0.62 Å above the plane defined by the four sulphurs.
