Abstract :The new giant Mo$_{36}$ polyoxomolybdate formulated as K$_{10}$[Mo$_{36}$O$_{110}$insert ignore into journalissuearticles values(OH);$_{6}$ insert ignore into journalissuearticles values(H$_{2}$O);$_{12}$].38 H$_{2}$O insert ignore into journalissuearticles values(1); was isolated by conventional solution method by the reaction of K$_{2}$MoO$_{4}$ and KNO$_{3}$ in aqueous solution insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(0); Å, b = 18.4485 insert ignore into journalissuearticles values(0); Å, c = 24.2424 insert ignore into journalissuearticles values(0); Å, $\alpha $ = 90.00$^{\circ}$, $\beta $ = 99.51$^{\circ}$, $\gamma $ = 90.00$^{\circ}$, V = 7285.79 insert ignore into journalissuearticles values(0); Å$^{3}$, and Z = 2. The refinement of the structure led to a residual factor R = 0.061 for 15,676 reflections.
