Abstract:[(Mes3Sn)2MoO4], a Monomeric Triorganotin Molybdate Mes3SnBr (Mes = 1, 3, 5‐trimethylphenyl) reacts with (NBu4)2[Mo6O19] in the presence of (NBu4)OH (in CH3CN as solvent) to form [(Mes3Sn)2MoO4]. Alternatively the title compound can be obtained from the reaction of [MoO2(acac)2] (acac = 2, 4‐pentadionate) with Mes3SnOH in isopropanol. [(Mes3Sn)2MoO4] forms monoclinic crystals, space group C2/c, with a = 2271.6(3) pm, b = 825.2(1) pm, c = 2739.9(5) pm, β = 90.96(2)°. The crystal structure consists of isolated molecules in which a tetrahedral MoO4 unit is connected to two terminal Mes3Sn groups. The Mo‐O distances range from 169.6(4) to 181.1(3) pm and the Sn‐O distance is 204.8(3) pm.
