New diphosphopentamolybdate (VI) (C$_6$H$_{14}$N)$_4$(NH$_4$)$_2$[P$_2$Mo$_5$O$_{23}$] · H$_2$O synthesis, crystal structure, experimental and theoretical studies
[摘要] The title compound (C$_6$H$_{14}$N)$_4$(NH$_4$)$_2$[P$_2$Mo$_5$O$_{23}$]·H$_2$O (1) was obtained by solution method using ammonium molybdate tetrahydrate, phosphoric acid and cyclohexylamine reagents in aqueous solution.Asingle-crystalX-ray diffraction study shows that the compound crystallizes in triclinic crystal systemwith space group P-1 and cell constants $a = 10.7178(4)\,\AA$, $b = 15.0809(6) \AA$, $c = 15.7745(9) \AA$, $\alpha = 71.510(6)^{\circ}$, $\beta = 75.508(2)^{\circ}$ and \gamma = 88.493(8)^{\circ}$. Also, in this article,we report results of thermal, electrochemical and spectral studies. In addition, the majority of theoretical properties were carefully studied.

Introduction Polyoxometalate encompasses a wide variety of oxo-transition metal anionic clusters with complex bases. In most cases the transition metals at the base of the polyoxometalates are V (V) (polyoxovanadate);Mo (VI) (polyoxomolybdate) and W [时效性]
