Two metal borates, Ba[MB4O8(OH)][middle dot]H2O (M = Al, Ga), with 3-D porous layers have been synthesized under hydro(solvo)thermal conditions, in which two MB4O11(OH) half-units link via Al-O-Al linkages to form the dimeric M2B8O20(OH)2 cluster unit. These clusters further connect with each other to form 3-D porous layers.
