Abstract: In the asymmetric unit of the title compound, (C16H38N2O6)[Zn(C3S5)2], two independent cations lie across inversion centers. In one of the cations, the three symmetry-unique O-H groups are disordered over two sets of sites with refined occupancy ratios of 0.701 (9):0.299 (9), 0.671 (8):0.329 (8) and 0.566 (7):0.434 (7). In the anion, the ZnII ion is coordinated in a distorted tetrahedral environment by four S atoms of two chelating 1,3-dithiole-2-thione-4,5-dithiolato ligands. The dihedral angle between the mean planes [maximun deviations = 0.022 (3) and 0.0656 (6) Å] of the two ligands is 87.76 (3)°. An intamolecular O-H...O hydrogen bond occurs in the disordered cation. In the crystal, O-H...O and O-H...S hydrogen bonds link the components into a two-dimensional network parallel to (0-11).
