Oct 14, 2013· Introduction. The structural chemistry of borates exhibits a respectable diversity, which comes from the ability of the boron atom to form trigonal-planar [BO 3] 3– groups and tetrahedral [BO 4] 5– groups. Moreover, links between these groups to form chains, layers, or highly condensed three-dimensional networks enlarge the amount of possible compounds.
