In the title compound, [Sn(CH3)2(C3H3N2S3)2], the SnIV atom is coordinated within a C2N2S2 donor set that defines a skew-trapezoidal bipyramidal geometry in which the methyl groups lie over the weakly coordinated N atoms. Two independent molecules comprise the asymmetric unit, each of which lies on a mirror plane that passes through the C2Sn unit.
