Trinuclear rhenium complexes with bridging nitrido ligands

Trinuclear complexes with bridging nitrido ligands between the rhenium atoms are formed when [ReN(Et2dtc)2(Me2PhP)] (Et2dtc- = N,N-diethyldithio-carbamate) reacts with TlCl or Pr(O3SCF3)3. [Cl(Me2PhP)2(Et2dtc)ReºN-Re(N)Cl2(Me2PhP)-NºRe(Et2dtc)(Me2PhP)2Cl] and [(Et2dtc)2(Me2PhP)ReºN-Re(N)-(Et2dtc)(Me2PhP)-NºRe(Me2PhP)(Et2dtc)2]+ contain two almost linear, asymmetric nitrido bridges. Additional, terminal nitrido ligands are located at the middle rhenium atoms.
