用X-射线衍射法测定了晶体Hg(SCH3)2的结构。晶胞尺寸为：a=19.80A；b=7.58A；c=7.80A。每个晶胞有8个公式单元，空间群为D2H15，Pbca。单式单元在晶体中的堆积表明，该化合物是一种含有弱硫醇桥的配位聚合物。每个汞都有两个最接近的硫原子，汞-S=2.36A和三个硫原子，汞-S=3.26A，组成一个不规则的四方锥体构型。
The structure of crystalline Hg (SCH3)2 has been determined by x‐ray diffraction analysis. The dimensions of the unit cell are: a=19.80 A; b=7.58 A; c=7.80 A. There are eight formula units per unit cell and the space group is D2h15, Pbca. The packing of the simple formula units in the crystal suggests the compound is a coordination polymer involving weak mercaptide bridges. Each mercury has two closest sulfur atoms with Hg–S=2.36 A and three sulfurs with Hg–S=3.26 A, comprising an irregular tetragonal pyramidal configuration.
