Adducts of triangular silver(i) 3,5-bis(trifluoromethyl)pyrazolate with thiophene derivatives: a weak interaction model of desulfurization

Abstract

π-Acidic triangular silver(I) 3,5-bis(trifluoromethyl)pyrazolate (Ag₃pz₃) can form 1 : 1 adducts with dibenzothiophene (DBT), 4,6-dimethyldibenzothiophene (DMDBT), benzothiophene (BT), and 2,5-dimethylthiophene (DMT), which are stabilized by weak Ag⋯S and Ag⋯C contacts and sometimes by π–π stacking and, therefore, may represent a weak interaction model for some adsorptive desulfurization processes.
