Crystal structure of a luminescent thiolated Ag nanocluster with an octahedral Ag₆⁴⁺core

Abstract

A yellow luminescent thiolate-protected Ag(14)(SC(6)H(3)F(2))(12)(PPh(3))(8) cluster was synthesized and structurally characterized by single-crystal X-ray analysis. The cluster contains an octahedral Ag(6)(4+) unit encapsulated by eight cubically arranged [Ag(+)(SC(6)H(3)F(2)(-))(2)PPh(3)] tetrahedra that share one corner (i.e. SC(6)H(3)F(2)(-)) between them.
