The four tris(amino)boranes represented by structure 1 with ethylene and/or trimethylene bridges have been prepared. Predictions that the smallest member of this series, 10-bora-1,4,7-triazatricyclo[,10]decane, would be highly strained were supported by the observation that this compound exists only as a tight dimer. 11 -Bora-1,4,7-triazatricyclo[,11]undecane is dimeric in solution but monomeric in the gas phase. The X-ray crystal structure and properties of 13-bora-1,5,9-triazatricyclo [,13]tridecane show that it has a stable planar BN3 aray.
