The title compound, (C18H26N2S2)[HgI4], consists of a discrete tetraiodomercurate(II) dianion and a bis[4-(trimethylammonio)phenyl] disulfide (Tab-Tab) dication. The geometry about the Hg atom in the dianion is a slightly distorted tetrahedral. The Tab-Tab dications are arranged parallel to each other. Three I atoms of the HgI42- dianion are connected to the adjacent H atoms of the methyl and phenyl groups of the Tab-Tab dications to form a two-dimensional network.
