Synthesis and characterization of a Mo/Ag/Rb heterotrimetallic cluster with double-cage architecture

The first Mo/ Ag/ Rb heterotrimetallic cluster has been synthesised by a self- assembly reaction involving [ Mo(2)O(2)S(2)edt(2)](2-), Ag+, Rb+, S2- and dibenzo- 18- crown- 6 ( DB18C6); the structure consists of two [{Mo(6)Ag(6)O(6)S(7)edt(6)} 2{Rb( DB18C6)}] (3-) units linked by Rb - C contacts.
