  Synthesis of Neutral Molecular Squares Composed of Bis(phosphine)platinum Corner Units and Dialkynyl Linkers. Solid-State Characterization of [Pt(μ-C⋮CC⋮C)(dppp)]₄

  摘要：

  Coupling of dichloroplatinum complexes with ethyne or butadiyne, catalyzed by CuI in the presence of Et2NH, leads to complexes of the types [Pt(C=CH)(2)L-2] (L-2 = dppe (1), dppp (2); L = PEt3 (3)) and [Pt(C=CC=CH)(2)L-2] (L-2 = dppp (4), dcpe (5); L = PEt3 (6)). Attempts to produce tetraplatinum species with ethynyl edges proved unsuccessful, but further coupling of the butadiynylplatinum complexes with [PtCl2L2] produces the neutral molecular squares [Pt(mu-Cequivalent toCCequivalent toC)(2)L-2](4) (L-2 = dppp (7), dcpe (8); L = PEt3 (9)). This two-step approach allows the synthesis of the unsymmetrical complexes [Pt-2(mu-Cequivalent toCCequivalent toC)(2)(PEt3)(2)L-2] (L-2 = dppp (10); dcpe (11)). The molecular structure of 7 reveals that each square has a puckered, butterfly-like structure. These pack in a face-to-face manner, generating series of channels that accommodate several solvent molecules. Coupling of trans-[Pt(Cequivalent toCCequivalent toC)(2)(PEt3)(2)] (6b) with [PtCl2L2] (L-2 = dcpe, dppp) leads to complexes assigned as neutral octaplatinum derivatives. The nitrogen-containing complexes [Pt(C=CC5H4N)(2)(dppp)] (14) and [Pt(Cequivalent toCC(6)H(4)CN)(2)(dppp)] (15) react with AgNO3 to produce Pt4Ag4 adducts.

  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

  The design and self-assembly of five new supramolecular complexes (a rectangle, a triangle, a hexagon, and two squares) are described. These assemblies incorporate carborane building blocks and were prepared in excellent yields (> 85%). The assemblies and building blocks were characterized with multinuclear NMR spectroscopy, electrospray ionization mass spectrometry, and elemental analysis. Isotopically resolved mass spectrometry data confirm the existence of the rectangle, triangle, and hexagon, and NMR data are consistent with the formation of all five assemblies. The X-ray structures of two linear carborane building blocks, 1,12-(4-C equivalent to C(C5H4N)(2)-p-C2B10H10 (1) and 1,12-(trans-(Pt(PEt3)(2)l)C equivalent to C)(2)-p-C2B10H10 (2), are reported: 1 is monoclinic, P2(1)/c, a = 10.6791(4) angstrom, b = 8.0091(14) angstrom, c = 11.6796(4) angstrom, beta = 107.8461(15)degrees, V = 950.89(5) angstrom(3), Z = 2; 2 is monoclinic, C2/c, a = 62.1128(10) angstrom, b = 22.0071(3) angstrom, c = 14.0494(2) angstrom, beta = 89.9411(8)degrees, V= 19204.4(5) A(3), Z = 16. Crystals of the linear linker 1 exhibit close pi-pi pyridine and pyridine-B (carborane) interactions, which are discussed.

  Six nanoscale molecular squares are reported. They are prepared in essentially quantitative yields via spontaneous self-assembly of preprogrammed 90 degrees angular units with diverse bimetallic linear linkers. Characterization was accomplished with multinuclear NMR and, in two cases, via ESI-FTICR mass spectral data. The size of these novel metallomacrocycles range from 3.6 nm (diagonal) and 2.6 nm (side) for the smallest to 4.7 nm (diagonal) and 3.4 nm (side) for the largest as estimated by extensible systematic force field calculations. The molecular squares incorporating alkynyl units as corners are able to complex four Ag+ ions via the pi-tweezer effect.
