A new member of Mo36- polyoxoanion’s family: synthesis, crystal structure, and physico-chemical properties of K10 [Mo36O110 (OH)6 (H2O)12 ].38 H2O

The new giant Mo$_{36}$ polyoxomolybdate formulated as K$_{10}$[Mo$_{36}$O$_{110}$(OH)$_{6}$ (H$_{2}$O)$_{12}$].38 H$_{2}$O (1) was isolated by conventional solution method by the reaction of K$_{2}$MoO$_{4}$ and KNO$_{3}$ in aqueous solution (pH = 1.8), at room temperature, and structurally characterized by single-crystal X-ray diffraction methods. The title compound crystallized in the monoclinic system, space group P2$_{1}$/n with unit a = 16.5180 (0) Å, b = 18.4485 (0) Å, c = 24.2424 (0) Å, $\alpha $ = 90.00$^{\circ}$, $\beta $ = 99.51$^{\circ}$, $\gamma $ = 90.00$^{\circ}$, V = 7285.79 (0) Å$^{3}$, and Z = 2. The refinement of the structure led to a residual factor R = 0.061 for 15,676 reflections.
