A new manganadecaborane has been isolated as a previously unsuspected product from the reaction of [Mn(CO)5Br] with K[B9H14]. The anion of tetrabutylammonium 5-bromo-6,6,6-tricarbonyl-6-manganadodecahydrodecaborate(1−), (C16H36N)[Mn(B9H12Br)(CO)3], has a nido cage structure. The Mn atom is bonded through three B - Mn bonds of similar length [2.221 (4), 2.224 (3) and 2.236 (3) î..] and two bridging H atoms. The position of the bromo substituent breaks the twofold symmetry of the cage found in simple analogues, and this is reflected in the B - B bond parameters.
