摘要: Abstract Methylmercury(II) xanthates, MeHgS(S)COR, with R=Et, iPr and CH2Ph, form unidimensional, supramolecular self-assembled, tape-like arrays in the solid state, based upon Hg⋯S intermolecular secondary interactions. In compounds R=Et individual molecules double chains (tapes) weakly interacting neighbouring arrays, while compound R=CH2Ph forms dimeric units, which are further associated into infinite tapes, not each other. Primary HgS bonds range 2.378(5)–2.391(3) A, intramolecular leading to chelation 3.179(5)–3.259(3) whereas interactions cover a broader range, from 3.403(4) 4.22(1) A.
