[Re(NBH2SBH3)(Me2PhP)(Et2dtc)]2 - A novel rhenium dimer with the unusual bridging (NBH2SBH3)4- ligand

Abram, U.

The title compound is formed during the reaction of [ReN(Me2PhP)(Et2dtc)2] (Me2PhP = dimethylphenylphosphine, Et2dtc- = diethyldithiocarbamate) with excess BH3 in tetrahydrofurane. Two ReV atoms are linked by two (NBH2SBH3)4- units which act as three-dentate ligand via N, S and H forming an 8-membered metallacycle with additional co-ordination of a hydrido H atom trans to the nitrogen atom. The ReN multiple bond length is 1.70(1) Å which is only slightly longer than in the starting compound [ReN(Me2PhP)(Et2dtc)2] (1.666(6) Å).
