| Abstract: | The double mercury salt Hg(C5H8N2)2]HgClI3]·C2H6OS was prepared and its structure characterized. The Hg(C5H8N2)2]2+ cation lies about an inversion centre and the HgClI3]2? anion lies on a mirror plane. Cations and anions are linked to form a one‐dimensional polymer by weak Hg?Cl interactions Hg?Cl 3.3744 (3) Å]. The mercury–carbene bond distance 2.076 (7) Å] is typical of a dicationic mercury–carbene species. |
