连二次硫酸是一种硫含氧酸 ，其中硫的氧化态为很低的 +1。它的结构为 HOSSOH，全部原子排成了一条线。 它是硫代亚硫酸 的异构体，不过能量较低。 其它异构体包括 HOS(=O)SH，HOS(=S)OH和 HS(=O)2SH。一氧化二硫，S2O，可以被认为是它的酸酐。 不像其它低氧化态的硫的含氧酸，连二次硫酸可以以纯净物存在，由硫化氢和二氧化硫在 −70 °C 下的 二氟二氯甲烷反应而成。 H2S + SO2 → H2S2O2 连二次硫酸可能会作为硫代次硫酸的一个互变异构体存在。 连二次硫酸的有机衍生物如：二甲氧基二硫、 二乙酸二硫 和双（三氟乙酸）二硫 是存在的。 连二次硫酸的共轭碱有连二次硫酸一氢根(1−) HSO−2 和连二次硫酸根(2−) SO2−2。

Dihydroxydisulfane or hypodithionous acid is a reduced sulfur oxyacid with sulfur in a formal oxidation state of +1. The structural formula is HOSSOH, with all atoms arranged in a chain. It is an isomer of thiosulfurous acid but is lower in energy. Other isomers include HOS(=O)SH, HOS(=S)OH, and HS(=O)2SH. Disulfur monoxide, S2O, can be considered as the anhydride. Unlike many of these other reduced sulfur acids, dihydroxydisulfane can be formed in a pure state by reacting hydrogen sulfide with sulfur dioxide at −70 °C in dichlorodifluoromethane. H2S + SO2 → H2S2O2

H2S + SO2 → H2S2O2 Dihyroxydisulfane may exist in an equilibrium with thiosulfurous acid. Organic derivatives such as dimethoxydisulfane, diaceto disulfide, and bis(trifluoroaceto) disulfide also exist. The conjugate bases are called disulfanediolate(1−) HSO−2 and disulfanediolate(2−) SO2−2.
