N2 - The X-ray crystal structure of (CH3NH3)4[(Mg(H2O)5)2(H6W12O42)]Br2·8H2O (1) obtained by a reaction of Li2WO4·H2O and Mg(NO3)2·6H2O in the presence of MeNH3Br is reported. Crystallographic parameters are: triclinic, space group P-1, a = 10.8280(4) Å, b = 12.4866(5) Å, c = 12.6201(5) Å, α = 108.501(1)°, β = 111.542(1)°, γ = 91.139(1)°, V = 1486.98(10) Å3, Z = 1, C4H66Br2Mg2N4O60W12, dx = 3.959 g/cm3, T = 150 K, R1 = 0.030 for 9914 Fo > 4δ(F) until 2θmax = 66.6° The structure contains tetraprotonated [H2W12O42]10– anions coordinated with {Mg(H2O)5}2+ cations as ditopic ligands via terminal oxygen atoms. The crystal structure also incorporates outer-sphere CH3NH3 + and Br– ions. The Mg2+ cations are in the octahedral environment, Mg–O(H2O) and Mg–O(W) bond lengths being 2.102(5)÷2.044(5) Å and 2.071(5) Å, respectively.
