摘要：

Faisant appel a la technique d'ionisation par desorption au laser du RuCl3 center dot 3H(2)O, on a realise la production en phase gazeuse de complexes anioniques du chlorure de ruthenium portant une seule charge. Dans le mode negatif, on ne peut detecter la presence des agregats de [RuxCly](-) qu'en l'absence de la composante matricielle. On a pu observer les cations de composition [RuCl4](-), [RuCl5](-), [Ru2Cl6](-), [Ru2Cl7](-), [Ru3Cl9](-), [Ru4Cl11](-) et [Ru5Cl12](-). En se basant sur des calculs selon la theorie de la fonctionnelle de la densite, on propose des structures plausibles pour chacun des agregats de chlorure de ruthenium dans lesquels des liaisons Ru-Ru et des ponts Cl sont des caracteristiques communes.
