An X-ray phase and X-ray structural analysis of M(Aet)2-8H2O compounds, where M(II) = Sr and Ba; (Aet)- = (C10H11N4O2S2) is the sulfaethiodole (2-(para-aminobenzene-sulfamido)-5-ethyl-1,3,4-thiadiazole) anion is carried out. Symmetry and unit cell parameters of Sr(Aet)2•8H2O and Ba(Aet)2-8H2O are found: P21/c, Z= 4, a = 10.390(2) Å, b= 14.609(3) Å, c = 21.931(5) Å, β = 92.42(2)°, R = 0.041; and P21/c, Z= 4, a = 9.793(2) Å, b = 15.408(4) Å, c = 22.553(6) Å, β = 94.98(2)° respectively. The considered compounds are isostructural. The structure of Sr(Aet)2-8H2O is fully studied; the crystals of the compound are composed of the complex centrosymmetric dimeric [(H2O)5Sr(Aet)2Sr(OH2)5]2+ cations, (Aet)- anions, and water molecules; the independent part of the structural formula of the compound is [Sr(Aet)(OH2)5](Aet)•3H2O. The sulfaethiodole anion is coordinated to the complexing metal atom by oxygen and nitrogen atoms with the formation of a four-membered ring.
