supramolecular chemistry leading to the formation of a single major product.
Keywords: arene–ruthenium(II); heterometallic cages; platinum metalloligand; self-assembly; supramolecular architectures; Introduction
Coordination-driven self-assembly of discrete architectures has evolved as a unique protocol to
heterometallic prismatic cages 3a and 3b obtained from the reaction of two arene–ruthenium(II) clips 1a and 1b and tritopic platinum(II) metalloligand 2 in methanol/chloroform mixture in 3:2 ratio (Scheme 1). Both cages were fully characterized by 1H, 31P, 195Pt, 1H,1H COSY, DOSY NMR, electrospray ionization
silver nitrate in methanol at room temperature for 3 hours gave the dinuclear arene–ruthenium(II) clips 1a,1b(NO3)2. As represented in Scheme 1, the self-assembly reactions of methanolic solutions of 1a,1b(NO3)2 and methanolic solution of the triplatinum metalloligand 2 at room temperature yielded the
