N2 - A novel crystalline microporous boron-aluminium chloride has been synthesized hydrothermally in the system B2O3-Al2O3-MxO-H2O(M=Li,Na,K,Mg,Ca,Ba. x = 1 or 2) and characterized by chemical analysis, ICP, XPS, XRD, MAS NMR, IR and adsorption. Unlike other microporous crystals, almost all with negatively charged or neutral framework, such as aluminasilicates and aluminophasphates, this microporous material possesses a positively charged framework. Chemical analysis shows that it has the molar composition 0.5B2O3 · 1.0Al2O3 · 0.40HC1 · 3.0H2O in which Cl−can be partially exchanged by Br−. The XRD pattern can be indexed with an orthorhombic unit cell with a=22.4, b=14.06 and c = 8.67 Å, and the basic building units are octahedral AlO6, triangular BO3and tetrahedral BO4. The determination of gas adsorption indicates that it possesses characteristic micropore adsorption properties. The pore size is about 3.0-4.3 Å.
