Abstract [en]
New heteroleptic mercury(ii) complexes [Hg4 (S2 CNPr2 )6 (NO3 )2 ] (1 ) and [Hg4 (S2 CNPr2 )4 Cl4 ] (2 ) were synthesized and characterized by single-crystal X-ray dif raction and 13 C and 15 N MAS NMR spectroscopy. In these complexes, the metal atoms are linked in pairs by bridging dipropyldithiocarbamate ligands (Pr2 Dtc) to form tetranuclear cations and molecules. The further structural organization of compound 1 to the polymeric chains [Hg4 (S2 CNPr2 )6 (NO3 )2 ]n occurs due to the linking of [Hg4 (S2 CNPr2 )6 ]2+ cations by pairs of bridging nitrate groups. The formation of the supramolecular polymeric structure of 2 is determined by pairwise secondary Hg⋯Cl bonds between the cyclic [Hg4 (S2 CNPr2 )4 Cl4 ] molecules, in which the central eight-membered metallocycle [Hg4 S4 ] adopts a distorted chair conformation. The thermal behavior of compounds 1 and 2 was studied by simultaneous thermal analysis.
