Self-assembly of metal-organic hybrid nanoscopic rectangles

The combination of an amide containing a linear ligand (L1) and an organometallic molecular clip (clip-1) leads to the self-assembly of a Pt-4 nanoscopic framework representing the. rst example of a Pt-based molecular rectangle (rectangle-1) incorporating amide functionality. A complementary approach was also followed to prepare a Pd(II)-based molecular rectangle (rectangle-2) by reaction of a donor organic rigid clip (clip-2) and trans-(PEt3)(2)Pd(OTf)(2) as the linear metal acceptor (L2). The Pd(II)-rectangle was characterised by multinuclear NMR and ESI-mass spectroscopy.
