A novel trinuclear Re(I) complex containing 1,3,4-thiadiazole-2,5-dithiolate: structural and spectroscopic properties

In the title complex [SSS(Re(CO)5)3](CF3SO3) (SSS = 1,3,4-thiadiazole-2,5-dithiolate), SSS adopts a two-S/one-N (κ3) coordination form, representing an unprecedented coordination pattern for this ligand. In addition, its solid-state structure confirms that an interesting anion π-interaction (2.880 A) between the N-heterocyclic ligand and the CF3SO3− anion is observed.
