Bonds hybridization and

We conclude this section by discussing systems where there are two types of hybrid orbitals. One such example is NIH, where there are three equivalent bond hybrids and one lone pair hybrid. Another example is the water molecule. As shown in Fig. 3.4.11, hybrids hi and/12 are lone pairs orbitals, while hybrids... 

This discussion shows that the widespread occurrence of regular tetra-hedrally and octahedrally coordinated metal ions calls for no special interpretation in terms of bond hybridization, and so forth. It is rather the other...

Note that we are making several assumptions based on chranical intuition or knowledge. The reason is that we want to go quickly without performing any computations. This ambiguity disappears, ifwe tnake real computations (e.g., using the Hartree-FotJc method). Then the chemical bonds, hybrids, and other items are obtained as a result of the computations. 

M(C0)4 fragment can be referred to a square antiprism with four outpointing hybrids, four bonding hybrids and a d 2 non-bonding orbital. Extended Huckel c eulations [8a] on M(CO)4 fragments predict 4, pyramidal structures for d (Q = 117.5°) and d Q = 122.5°). The nodal cone of d a occurs at 0 = 125.27°.
