| 摘 要： | 1 INTRODUCTION The contemporary studies on POMs reveal theirspecial properties which endow these materials withwide range of applications, such as catalysis, medi-cine1], material science2], etc. Current research inte-rest mainly focuses on the development of solid ma-terials with unusual structural complexity and con-comitant diversity of applicable properties. A series ofmolybdate oxide phases have been synthesized, inwhich the polymolybdate anions are linked intoinfinite 1-, 2- or 3…

A New One-dimensional Chain Compound Constructed by {Mo8O28} units via Corner-sharing |

| Abstract: | The title compound, {(H3O)4(NH4)4Mo8O28]·2H2O}n 1, has been synthesized
rature, and its crystal structure was determined by X-ray single-crystal analysis with the following
crystallographic data: monoclinic system, space group P21/n, a = 9.5234(6), b = 11.3235(8),
c = 14.8812(10) (A), β = 107.467(2)°, V= 1530.77(18) (A)3, Z= 4, F(000) = 1336,μ = 3.293 mm-1
and Dc= 3.037 g/cm3. The final R = 0.0619 for 2691 observed reflections (I ＞ 2σ(I)). X-ray crys
tal structure analysis showed that the novel one-dimensional chain compound is built up by basic
{ Mo8O28 } units via singleμ2-O, and such chains are further linked into a three-dimensional net
work by hydrogen bonds. |
