  • Title: The synthesis of new 60 degrees organometallic subunits and self-assembly of three-dimensional M3L2 trigonal-bipyramidal cages.
    Author: Yang HB, Ghosh K, Arif AM, Stang PJ.
    Journal: J Org Chem; 2006 Dec 08; 71(25):9464-9. PubMed ID: 17137374.
    Abstract:
    By employing the coupling reaction of trans-PtI2(Et3)2 with C-H bonds in alkynes as the key step, two new 60 degrees organometallic subunits with different size from 3,6-dibromophenanthrene were prepared in reasonable yields. The X-ray structures of both di-Pt(II) diiodide complexes showed that they were indeed suitable candidates for 60 degrees building units. By utilizing these novel linkers as ditopic acceptor subunits, three M3L2 trigonal-bipyramidal (TBP) cages were formed. All three TBP cages were characterized with multinuclear NMR and electrospray ionization mass spectrometry (ESI-MS) along with element analysis.
