Heavier main-group elements like T1(I), in complex compounds, generally exhibit a stereochemically active lone pair when the donor atoms are nitrogen, oxygen or fluorine [23]. 

Tliis information is most completely given, in notation, by making carbon the dominant or grouping element in non-nitrogenouB compounds, and nitrogen in the remaining organic compounds. 

When we compare the first two elements of Group V, nitrogen and phosphorus, the outer valence shell looks quite similar (2s22p3 and 3s2 3p3, respectively), but the physical and chemical properties of the two elements and their compounds are extremely different (B-76MI11700). 

Until recently only a handful of main group elements — carbon, nitrogen, oxygen and sulfur — were known to be able to form stable (p-p)rc bonds. The complete lack of such bonds in compounds of the heavier elements had been rationalized by theoretical treatments by Pitzer u and Mulliken 2). Indeed, many commonly used textbooks of inorganic chemistry contain statements such as,. . p-p-n bonding is of little importance in the third and higher period elements,3). 

Azide compounds of hypervalent main group elements such as Si and Ge are also highly explosive [83,84], but their structures and energetics have not been widely explored. Quite recently, the crystal structure of the Si(N3)62 anion has been reported, which has 90% nitrogen content, enough to be a possible high-energetic material candidate[83,84]. It is noted that Si(N3)62 (E = Ge, Pb) have been synthesized and are structurally known [83],...
