5-Phenyl-1,2,5-dithiazepane

“…The mean average bond length for C-S-S-C bonds from 99 samples, reported by (Allen et al, 1987) is 2.048 Å. The torsion in the C-S -S-C bonds is -83.89 (7)°, this compares similarly to the C-S-S-C torsion in the 7-membered ring disulfide 1,2,4,6-tetrathiacycloheptane reported in (Pickardt et al, 2006), which has a C-S-S-C torsion of -89.4 (2)°.…”

“…The seven-membered ring adopts a chair conformation, as it does in the cyclic disulfide compound reported by Pickardt et al (2006). The dominant intermolecular interactions are between S1···S2 of symmetry-related molecules.…”

Cadmium-113 NMR studies on homoleptic complexes containing thioether ligands: the crystal structures of [Cd([12]aneS4)2](ClO4)2, [Cd([18]aneS4N2)](PF6)2 and [Cd([9]aneS3)2](PF6)2

“…The ligands ttn and [12]aneS 3 were prepared by the reported procedures. 58, 59 The previously reported Cd(II) complexes [Cd( [9]aneS 3 ) 2 ](ClO 4 ) 2 (3b), 13,60 [Cd( [16]aneS 4 )](ClO 4 ) 2 (8), 10 [Cd( [10]aneS 3 ) 2 ](ClO 4 ) 2 (9), 12 [Cd( [15]aneS 5 )](ClO 4 ) 2 (10) 11 and [Cd( [9]aneN 3 ) 2 ](ClO 4 ) 2 (11) 33 were prepared as previously reported. Combustion analyses were performed by Atlantic Microlab, Atlanta, GA. Infrared spectra were obtained on a Nicolet FTIR using dry pre-weighed KBr packets (500 mg) and an ATR accessory.…”
