No structure of a stable monomeric iminoalane is currently available. However, the p-diketiminate stabilized monomeric [(L)]AINC6H3(C6H2Pr 3-2,4,6)2-2,6] (L = HC C-(Me)N(Dipp) 2) is believed to have a very similar structure to its gallium analogue (cf. Section 8.3.5) which has a very short Ga—N distance of 1.701 A consistent with Ga—N multiple bonding. It readily underwent intramolecular additions to the Al—N bond to give crystalline products. For an account of the chemistry of A1(L), see Ref. 184. 

The structure of the few indium(II) compounds identified by early workers is one of the classical problems in group III chemistry, (cf. gallium, Section 25,3.3.3). It is now clear that both M—M-bonded compounds and ionic mixed valence species exist, but the factors which govern the relative stability of these species still remain to be elucidated. 

Since discovery of MCM-41 materials [1,2] many researchers have been concentrated on the improvement of their quality and properties by incorporating heteroatoms such as titanium [3-5], boron [6,7], vanadium [8], gallium [9], and recently lanthanides (mainly La and Ce) [10-13]. Incorporation of these elements into the MCM-41 structure influences its stability as well as adsorption and catalytic properties [13]. The presence of silanol groups on the surface of these mesoporous materials allows for bonding of organic and inorganic ligands [14-16].
