metallacalixarene platinum bistriflates with bipyridine as well as other bidentate connector ligands results in the formation of tetranuclear macrocycles via self-assembly that combine crown ether and calixarene chemistry with molecularsquares. Multinuclear NMR spectroscopy and electrospray mass spectrometry are employed to characterize these unique supramolecular species. The calixarene metallamacrocycles

The preparation of the reactive diaqua complexes of (bis(diphenylphosphino)ferrocene)palladium(II) and -platinum(II) bis(triflates) and the X-ray crystal structure of [Pt(dppf)(H2O)2][OTf]2 (dppf = 1,1‘-bis(diphenylphosphino)ferrocene) are reported. Interaction of these complexes with 2,7-diazapyrene produced novel octanuclear square-shaped metallomacrocycles. Modular self-assembly of [Pd(dppf)(H2O)2][OTf]2

characterization of various optically active nanoscale-size tetranuclear assemblies held together by coordination bonds is described. Interaction of bis[4-(4‘-pyridyl)phenyl]iodonium triflate and bistriflates of chiral transition metal (Pd(II) or Pt(II)) bisphosphines resulted in the formation of chiral hybrid iodonium-transition metal molecular squares. Restricted rotation of the coordinated bis[4-(4‘-pyridyl)phenyl]iodonium

organometallic macrocycles, and other similar complexes currently under investigation, will be potentially useful devices, particularly in the area of organic synthesis and organometallic catalysis. Furthermore, complex 7 is of significant interest in regard to its potential nonlinear optical and electronic properties, given the presence of metal-alkynyl units and possible pi}-conjugation within the macrocycle
