The title compound, [Rh2Br2(C16H23B9N2S)(2)], has crystallographic inv
ersion symmetry with two close twelve-vertex {3,1,2-RhC2B9}-cages brid
ged through the Rh atoms by two Br atoms. Each Rh atom is bonded to th
e S atom of an {-SC(NHPh)-N(Ph)CH2-} ligand whose methylene C atom in
turn is bonded to a B atom of the RhC2B9 cage, thereby forming a six-m
embered RhSCNCB exo-cage ring. Principal distances include Rh-Br 2.590
3(7), 2.6702(7) and Rh-S 2.3471(10)Angstrom. The distances within the
RhSCNCB ring are (in sequence) S-C 1.725(4), C-N 1.331(5), N-C 1.473(5
), C-B 1.586(6) Angstrom.
