heal.abstractThe pressure dependences of the Fourier transform micro-Raman spectra of four heterocyclic thioamides [{(bztzdtH)I-2} . I-2] (1) (bztzdtH = benzothiazole-2-thione), [(bztzdtH)I-2] (2), [{(tzdtH)(2)I+} . I-3(-) . 2I(2)] (3) (tzdtH = thia- zoline-2-thione), and [{bzimtH)I-2}(2) . I-2 . 2H(2)O] (4) (bzimtH = benzimidazole-2-thione) have been studied between ambient pressure and 50 kbar. For 1, generation of I-3(-) ions through disproportionation reactions is evident as the pressure is increased. There are empirical linear correlations between the frequency and (I-I) bond length and the applied pressure. The iodine adduct of thioamide 2 is more sensitive to pressure when compared to the 1 or 4 iodine adducts. This difference in behavior may be attributed to differences in crystal structures or to a lower I-I bond order. Monitoring of other vibrational transitions of the thiomide structure reveals several less important pressure dependences. (C) 2002 Elsevier Science B.V. All rights reserved.en
