The title compound, C(11)H(18)N(2)S(4), was unexpectedly obtained during studies on the reactivity of the complex tris-(acac-κ(2)O,O')gallium(III) (acac is acetyl-acetonate) with C(4)H(8)NCS(2)H in dichloro-methane. The title compound shows disordered two pyrrolidine rings with major and minor occupancies of 0.546 (4) and 0.454 (4). Two (pyrrolidin-1-yl)carbothio-ylsulfanyl units are linked together through a methyl-ene C atom and weak C-H⋯S inter-actions are found.
