Trinuclear cationic silver nanoclusters based-on bis-(phosphine) ligands and stabilized by CF₃SO₃⁻anions

Abstract

Three trinuclear silver nanoclusters, [Ag3(dppm)3(tBuC≡C)](CF3SO3)2 (1), [Ag3(dppm)3(CO3)(CH3OH)](CF3SO3)•H2O (2) and [Ag3(dppm)3(Cl)2](CF3SO3)•3DMF (3) (dppm = 1, 2-bis-(diphenylphosphino)methane) have been obtained, which also have been characterized by a series of techniques including single-crystal...

“…Anions, as opposed to cations and neutral templates, have attracted the attention of more and more scientists in recent decades, using them to regulate the formation of cluster compounds and to determine the size and shape of the resulting clusters [37] . The anion mainly contains halogen ions, [38] oxyacid anions/polyanions (such as CrO 4 2− , [39,40] CO 3 2− , [41–50] NO 3 − , [51] MoO 4 2− , [35] [Mn III Mn IV 2 Mo 14 O 56 ] 17− , [52] Mo 6 O 22 8− , [53] [Mo 20 O 66 ] 12− , [54] [EuW 10 O 36 ] 9− , [55] VO 4 3− , [56] AsO 4 3− , [57] SO 4 2− , [58,59] P 5 W 30 , [60] [V 10 O 28 ] 6−[61] ), and organic anions (C 4 O 4 2− , [62] C 2 O 4 2−[63] ), etc. Among them, the carbonate ion (CO 3 2− ) is a perfect anion template.…”
