Vibrational spectra of 2-halo-1,3-dithia-2-metallo-cyclopentanes

Structural characteristics of 2-halo-1,3,2-dithiarsenic compounds and tris-(pentafluorophenylthio)-arsen

“…The IR spectrum for compound 1 is strikingly similar in compounds 2-6. The C-S stretches at 669 and 644 cm À1 and As-S stretch at 450 cm À1 are indicative of the presence of a ring [16,17].…”

Synthesis and characterization of a rare arsenic trithiolate with an organic disulfide linkage and 2-chloro-benzo-1,3,2-dithiastibole

“…The carbons with no protons are not seen due to a lack of the NOE effect. Compound 1 displays the characteristic IR bands seen in organo-arsenic thiolates [9,10]. The band at 659 cm À1 is indicative of C-S bonds and the peaks although weak at 479 and 425 cm À1 are in the correct range for the As-S bonds in the ring.…”
