Boron oxygen compounds

The structure of solid boric acid. The hydrogen bonds holding the B(OH)3 units together are 175 pm long. One B(0H)3 unit is indicated by a broken-line triangle. 

This is quite correct. However, the ionization of B(OH)3 in water is unusual H+(aq) is generated by abstracting OH from a water molecule  

boric acid acts as a Lewis acid, accepting a non-bonded pair from the Lewis base OH , and forming four tetrahedrally disposed B—O bonds (Structure 9.7). 

boron can occur in three- or four-fold coordination with oxygen atoms. 

What would be a more correct formula for the compound

Boron oxides and their derivatives are technologically important and are relatively inexpensive to produce since, as noted earlier, essentially all boron in Nature is in oxygenated form. Boron-oxygen compounds contain predominantly trigonal planar B03, and to a lesser degree tetrahedral B04 units, as in the borate anions in Fig. 5-25.

BOF " (B-F, 1-43 A, B-0, 1-435 A) in salts such as BaBOF3.( > The B(OH) ion and many examples of tetrahedral BO4 coordination groups are mentioned under boron-oxygen compounds later in this chapter. 

As variously mentioned, considerable parts of the subject described in this chapter, especially concerning boron-oxygen compounds, have been treated in the literature before 1980. However, as some important aspects, particularly those concerning syntheses, were not considered in CHEC-I, synthetic principles, describing the route to the various types of rings, will be taken into consideration. 

However, many boron-oxygen compounds are still named as derivatives of boric acid, B(0H)3 boronic acid, HB(0H)2 and borinic acid, (H2B(0H)). We will not use this method for naming boronoxygen compounds.
