Two novel metal borates with three-dimensional open-framework layers constructed from [M2B8O20(OH)2] (M = Al, Ga) cluster units.
Two novel metal borates, Ba[MB4O8(OH)]·H2O (M = Al/Ga), with a three-dimensional open-framework layer have been synthesized under hydro(solvo)thermal conditions, in which the Al(3+)/Ga(3+) ions have been successfully introduced into the oxoboron cluster backbone and further linked together to form the open-framework layer composed of the [M2B8O20(OH)2] cluster units. The half-unit [MB4O11(OH)] can be viewed as analogous to the known [B5O9(OH)] cluster. Interestingly, the rare M-O-M linkages play a crucial role in forming the open-framework layer.
