Ethynide-stabilized high-nuclearity silver(i) sulfido molecular clusters assembled using organic sulfide precursors†
Abstract
Inexpensive 1,1′-thiocarbonyldiimidazole and di(2-pyridyl) thionocarbonate have been used as respective sulfide precursors to assemble unprecedented high-nuclearity ethynide-stabilized silver(I) sulfido molecular clusters [Ag9S6@Ag36(CCtBu)32(H2O)2] [Ag(imidazole)(CH3OH)(H2O)](BF4)2·8H2O·2CH3OH (1) and [Ag120S24(PhCC)52Cl4(2-pyridone)10(H2O)8](H3O)4(SiF6)8(BF4)4·CH3OH·22H2O (2), the latter being the largest isolated silver(I) ethynide cluster reported to date.
