9 Aluminium to thallium salts of oxoacids, aqueous solution chemistry and complexes 

The reaction of LiHPhP-BH3 with MezHN-BHzCl leads to a horon-containing product A. The highest mass peak in the mass spectrum of A is at m/z = 180. The P NMR spectrum of a solution of A exhibits a broadened doublet at S -54.8 ppm (7344 Hz), 

Molecular species containing group 13 metal-nitrogen bonds 

A number of related Ga-containing cages are known, as well as a few Tl—N clusters, e.g. Tl2(MeSi)2(N Bu)4,13.37. However, in the latter and related compounds, the Tl atoms do not carry terminal substituents, another manifestation of the thermodynamic 6s inert pair effect (see Box 13.3). 

Multiply-bonded compounds of the type observed for boron are not a feature of the later group 13 elements.
