An aqueous synthesis, involving the reduction of the VO3- anion in a mild alk. pH in the presence of α-Bi2O3, led to the formation of a fully reduced polyoxovanadate (POV) capsule, with CO32- anion encapsulation in its internal cavity, in the compound [Na6(H2O)24][H8VIV15O36(CO3)]·3N2H4·10H2O (1). This CO32- anion encapsulation, the source of which is absorbed aerial CO2 in the pertinent aqueous alk. reaction mixture, occurs only in the presence of α-Bi2O3. Compound 1 crystals, upon exposure to HCl acid vapor, exclude CO2 gas that can react with the Grignard reagent (PhMgBr) to form triphenylcarbinol and benzoic acid; during this solid-vapor interface reaction, compound 1 itself transforms into an amorphous material that includes the Cl- anion but could not be characterized unambiguously. Thus, we have synthesized a chloride ion (Cl-) encapsulated compound [Na10(H2O)24][H3VIV15O36(Cl)]·6H2O (2) in a direct synthesis protocol, which has been characterized by crystallog. as well as by other spectroscopic methods. Compounds 1 and 2, each having fifteen vanadium(IV) centers, exhibit interesting magnetism in their solid states. The temperature-dependent magnetic susceptibilities for compounds 1 and 2 have been recordred at 0.1 T at of 3-300 K. The temperature-dependent magnetic susceptibilities of compounds 1 and 2 are shown in the form of χM vs.T and their product χMT vs.T plots.
