We succeeded to prepare novel [Mo{sub 36}O{sub 112}(H{sub 2}O){sub 16}]{sup 8-} ({l_brace}Mo{sub 36}{r_brace}) compounds by using 1,3-diamino-2-propanol ({beta}OHC{sub 3}-DA) and 1,3,5-tris(aminomethyl)benzene (MES-TA)+1,3-diaminopropane (C{sub 3}-DA) as linkers, and determined their crystal structures. We have confirmed they have unique two-dimensional (2-D) molybdenum oxide frameworks, which are formed by condensation of {l_brace}Mo{sub 36}{r_brace}s. Side-staggered arrays of {l_brace}Mo{sub 36}{r_brace}s, connected in lying position by eight bridges per a {l_brace}Mo{sub 36}{r_brace}, are formed in the compound with {beta}OHC{sub 3}-DA, while herringbone arrays of {l_brace}Mo{sub 36}{r_brace}s, connected in standing position by four bridges per a {l_brace}Mo{sub 36}{r_brace}, are built in the compound with MES-TA+C{sub 3}-DA. The latter compound exhibited non-stoichiometric property, and its composition and cell parameters varied depending on the relative concentration of MES-TA in the mother solution. - Graphical abstract: The image shows a variety of 2-D molybdenum oxide frameworks consisting of nanosized polyoxometalate anion [Mo{sub 36}O{sub 112}(H{sub 2}O){sub 16}]{sup 8-} ({l_brace}Mo{sub 36}{r_brace}), obtained by our fabrication techniques. The variations are expected to provide diversity in physical properties of the frameworks.
