Carboxy bridges link the independent molecules of the title compound,
catena-poly [trimethyltin-mu-(N,N-dimethylthiocarbamoylthio) acetato-O
:O'], [Sn-(C5H8NO2S2)(CH3)(3)], in a linear chain along the x axis; bo
th five-coordinate Sn atoms (two independent molecules in the asymmetr
ic unit) show trans-trigonal bipyramidal coordination.
