Abstract

Crystals of 1,4,7,10-tetrathiacyclododecane silver(I) trifluoromethanesulfonate, Ag(C8H16S4)- (CF3SO3), 1,4,7,10-tetrathiacyclododecane iodo mercury(II) hexaiododimercurate(II)methylene chloride [HgI(C8H16S4)][Hg2I6] · CH2Cl2, 1,4,7,10,13,16-hexathiacyclooctadecane silver(I) trifluoromethanesulfonate [Ag(C12H24S6)](CF3SO3), 1,4,7,10,13,16-hexathiacyclooctadecane diiodocadmium, [Cd(C12H24S6)I2], and bis-3,6,9,14-tetrathiabicyclo[9.2.1]tetradeca-11-13-diene silver(I) trifluoromethanesulfonate [Ag(C10H14S4)2](CF3SO3) were obtained by reaction of solutions of the ligands and the appropriate metal salts and their X-ray crystal structures determined.

Synthesis, Stability Constant Determination, and Structural Study of Some Complexes of a Zinc Triad Containing Pyridyl‐amine‐quinoline and Pyridyl‐thio‐quinoline

“…Search (a) returned nine entries. In these structures, the Hg II -S(thioether) distances vary from 2.491 [20] to 2.822 [21] Å. (2)], again within the experimental range, and are similar to those found in the cation reported in ref.…”

Syntheses, structures, and complexation of cis‐ and trans‐cycloheptane‐1,2‐diyl‐fused crown thioethers ([12]ansS4)

“…The distances of diagonal sulfur atoms are 5.061(1) Å for S2···S4 and 4.757(1) Å for S1···S3 Å, and those of neighboring sulfur atoms are in the range of 3.427(1)–3.520(1) Å. These parameters are similar to those of [Ag(12ansS 4 )]OTf except the difference of the counter anions and the part of the fusion of rings 15. The cycloheptane ring takes a twist‐chair conformation.…”

“…Keeping in mind that S‐C‐C‐S parts are all anti in free 12ansS 4 8 and, in contrast, all gauche in the complex with silver trifluoromethanesulfonate (AgOTf) 15, one can expect that it is advantageous to cis ‐ 2 , which has one constrained gauche orientation, to form complexes with metal cations compared with all‐anti (±)‐ trans ‐ 2 , if their most stable conformations in solution are similar to those in the crystalline state. Competitive complexation of cis ‐ 2 and (±)‐ trans ‐ 2 was performed using an equimolar amount of AgOTf in acetonitrile‐ d 3 .…”
