Bimolecular gas-phase reactions between transuranium actinide ions and neutral reagents are employed to obtain thermochemical information. The initial actinide sulfide studies have focused on obtaining the 298 K bond dissociation energy for the CmS<jats:sup>+<\/jats:sup> ion, D[Cm<jats:sup>+<\/jats:sup>-S] = 475\u00b137 kJ mol<jats:sup>-1<\/jats:sup>; from this result and an estimate of IE[CmS] \u2248 IE[CmO] + 0.5 eV, we obtain D[Cm-S] = 563\u00b164 kJ mol<jats:sup>-1<\/jats:sup>. The bond dissociation energies, D[Cm<jats:sup>+<\/jats:sup>-S] and D[Cm-S] are approximately 200 kJ mol<jats:sup>-1<\/jats:sup> and 150 kJ mol<jats:sup>-1<\/jats:sup> lower than for the corresponding oxides, CmO<jats:sup>+<\/jats:sup> and CmO. The nature of the bonding in the CmS<jats:sup>+<\/jats:sup> ion appears to be generally similar to that in other oxophilic metal sulfides. Comparisons with previous bond dissociation energies reported for ThS and US may suggest a difference in the An-S bonds for these early actinide sulfides as compared with CmS.<\/jats:p>","DOI":"10.1557\/proc-1264-z02-04","type":"journal-article","created":{"date-parts":[[2010,8,13]],"date-time":"2010-08-13T10:30:03Z","timestamp":1281695403000},"source":"Crossref","is-referenced-by-count":0,"title":["Thermochemistry of Elementary Actinide Sulfide Molecules: A Gas-Phase Study of Curium Sulfide"],"prefix":"10.1557","volume":"1264","author":[{"given":"Cl\u00e1udia C.
