The solid-state structure of the rhodium complex (dimethylamine-dimethylaminoborane-borane-kappa H-2,H')dihydridobis-(triisopropylphosphane-kappa P)rhodium(III) tetrakis[3,5-bis(trifluoromethyl)phenyl]borate, [RhH2(C4H18B2N2)(C9H21P)(2)](C32H12BF24), is reported. The complex contains the linear diborazine H3B center dot NMe2BH2 center dot NMe2H, a kinetically important intermediate in the transition-metal-mediated dehydrocoupling of H3B center dot NMe2H, ultimately affording the dimeric amino-borane [H2BNMe2](2). The structure of the title complex contains a distorted octahedral Rh-III centre, with mutually trans phosphane ligands and cis hydride ligands. The diborazine is bound through two Rh-H-B sigma-bonds and exhibits a gauche conformation with respect to the B-N-B-N backbone.
