A white solid was isolated and colourless single crystals of the title compound for the SC-XRD analysis were obtained from a solution in (methanesulfinyl)methane (common name: dimethyl sulfoxide, DMSO) with a hexane overlay. The Hg\n                    <jats:sup>II<\/jats:sup>\n                    metal center is fourfold coordinated in a distorted tetrahedral geometry by two neutral thiosemicarbazone derivatives, acting as \u03ba\n                    <jats:italic>S<\/jats:italic>\n                    -donors, and two chlorido ligands. The complex molecule exhibits a sequence of four intramolecular hydrogen-bonded rings, formed by two interactions of the N\u2014H...Cl type, with graph-set motifs of\n                    <jats:italic>S<\/jats:italic>\n                    (6) and showing a chelate-like coordination environment around the metal center, and two additional interactions of the N\u2014H...N type with\n                    <jats:italic>S<\/jats:italic>\n                    (5) graph-set motifs.

The Hirshfeld surface analysis suggests that the major contributions for the crystal cohesion are the H...H (40.4%), H...Cl\/Cl...H (14.5%), H...C\/C...H (11.3%), H...O\/O...H (10.6%) and H...S\/S...H (9.2%) intermolecular contacts, with the surface being mapped over the\n                    <jats:italic>d<\/jats:italic>\n                    <jats:sub>norm<\/jats:sub>\n                    , shape-index and curvedness properties.\n                  <\/jats:p>","DOI":"10.1107\/s2056989026004822","type":"journal-article","created":{"date-parts":[[2026,5,13]],"date-time":"2026-05-13T08:15:06Z","timestamp":1778660106000},"page":"656-664","update-policy":"https:\/\/doi.org\/10.1107\/cm_01","source":"Crossref","is-referenced-by-count":0,"title":["Synthesis, crystal structure and Hirshfeld analysis of the bis{(\n                    <i>E<\/i>\n                    )-2-[1-(benzo[\n                    <i>d<\/i>\n                    ][1,3]dioxol-5-yl)ethylidene]-\n                    <i>N<\/i>\n                    -ethylhydrazine-1-carbothioamide-\u03ba\n                    <i>S<\/i>\n                    }dichloridomercury(II) complex"],"prefix":"10.1107","volume":"82","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5522-7913","authenticated-orcid":true,"given":"Renan Lira de","family":"Farias","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3624-0535","authenticated-orcid":true,"given":"Johannes","family":"Beck","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J\u00f6rg","family":"Daniels","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9354-280X","authenticated-orcid":true,"given":"Adriano Bof de","family":"Oliveira","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"329","published-online":{"date-parts":[[2026,5,15]]},"reference":[{"key":"yz2078_bb1","unstructured":"Alcock, N.
