X-ray phase and X-ray spectral analyses are performed for newly synthesized M(Aet)2·11H2O compounds, where M(II) = Mn, Mg, and Mg0.5Mn0.5, (Aet) = (C10H11N4O2S2), the anion of ethazol (2-(paraaminobenzene sulfanilamide)-5-ethyl-1,3,4-thiadiazole). It is found that these compounds are isostructural. In the third compound, Mg and Mn statistically substitute for each other and the substitution takes place at any ratio of these metals. The structure of crystals of the [Mn(OH2)6](Aet)2·5H2O compound is studied: a = 17.160(2) Å, b = 14.115(1) Å, c = 15.130(2) Å, β = 98.23(3)°, P21/n, Z = 4, R(F) = 0.045. The compound consists of complex [Mn(OH2)6]2+ hexaaqua cations, (Aet) anions, and five water molecules.
