Two New Borates Built by Different Types of {B9} Cluster Units
Two new belt-like borates Na 4 [B 9 O 14 (OH) 3 ]·0.5H 2 O( 1 ) and Na 5 [B 9 O 14 (OH) 4 ]( 2 ) have been synthesized under solvothermal conditions. Both compounds contain unprecedented B 9 O 16 (OH) n ( n +5)− [ n =3( 1 ), 4( 2 )] clusters, which are constructed from four B 3 O 3 rings via three B...
