The title compound, [Cd(CH4N2S)(6)](ReO4)(2).H2O, is built up of isola
ted centrosymmetric [Cd{SC(NH2)(2)}(6)](2+) octahedra, ReO4- tetrahedr
a and water molecules packed most densely in the ac plane. Two of the
three nonequivalent thiourea molecules are almost parallel and the thi
rd one is perpendicular to the ac plane. The structural units are held
together by a complex network of intra-and intercluster hydrogen bond
s.
