Abstract

Slow evaporation in air of the solution of trimeric perfluoro-ortho-phenylene mercury (1) and 2,1,3-benzothiadiazole (2) in THF affords a complex 1·22·H2O0.59 (3). A complex of 1 with di(tetrahydrofur-2-yl) ether (4; probably, a THF oxidation product) with a composition of 1·42 (5) is detected as a minor admixture to 3. The structure of complexes 3 and 5 is determined by single crystal XRD. In complex 3, a molecule of 1 participates in Hg…N and πF…H-C interactions with one molecule of 2 and in the πF…πH stacking interaction with another. Complex 5 is formed by Hg…O interactions with the participation of both heterocycles of a molecule of 4.
