Quecksilber(II)‐chlorid‐ und ‐iodid‐Komplexe von Dithia‐ und Tetrathiakronenethern

Mercury(II) Chloride and Iodide Complexes of Dithia‐ and Tetrathiacrown Ethers The complexes [(HgCl 2 ) 2 ((ch) 2 30S 4 O 6 )] ( 1 ), [HgCl 2 (mn21S 2 O 5 )] ( 2 ), [HgCl 2 (ch18S 2 O 4 )] ( 3 ) and [HgI(meb12S 2 O 2 )] 2 [Hg 2 I 6 ] ( 4 ) have been synthesized, characterized and their crystal structures were determined. In [(HgCl 2 ) 2 ((ch) 2 30S 4 O 6 )] two HgCl 2 units are discretely bonded within the ligand cavity of the 30‐membered dichinoxaline‐tetrathia‐30‐crown‐10 ((ch) 2 30S 4 O 6 ) forming a binuclear complex. HgCl 2 forms 1 : 1 “in‐cavity” complexes with the 21‐membered maleonitrile‐dithia‐21‐crown‐7 (mn21S 2 O 5 ) ligand and the 18‐membered chinoxaline‐dithia‐18‐crown‐6 (ch18S 2 O 4 ) ligand, respectively. The 12‐membered 4‐methyl‐benzo‐dithia‐12‐crown‐4 (meb12S 2 O 2 ) ligand gave with two equivalents HgI 2 the compound [HgI(meb12S 2 O 2 )] 2 [Hg 2 I 6 ]. In the cation [HgI(meb12S 2 O 2 )] + meb12S 2 O 2 forms with the cation HgI + a half‐sandwich complex.
