The title compound, bis[dithiobis(formamidinium)] hexabromidoruthenium dibromide trihydrate, [(NH2)(2)CSSC(NH2)(2)](2)[RuBr6]Br-2 center dot 3H(2)O, crystallizes in the orthorhombic system, space group Cmcm, Z = 4. The [RuBr6](2)(-) anionic complex has an octahedral structure. The Ru-Br distances fall in the range 2.4779 (4)-2.4890 (4) angstrom. The S-S and C-S distances are 2.0282 (12) and 1.783 (2) angstrom, respectively. The H2O molecules, Br- ions, and NH2 groups of the cation are linked by hydrogen bonds. The conformation of the cation is consolidated by intramolecular O-H center dot center dot center dot Br, O-H center dot center dot center dot O, N-H center dot center dot center dot Br and N-H center dot center dot center dot O hydrogen bonds. The [(NH2)(2)CSSC(NH2)(2)](2+) cations form a hydrogen-bonded system involving the Br- ions and the water molecules. Two Br- anions form four hydrogen bonds, each with the NH2 groups of two cations, thus linking the cations into a ring. The rings are connected by water molecules, forming N-H center dot center dot center dot O-H center dot center dot center dot Br hydrogen bonds.
