  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.

  Lithiation (LiBut) of 2 gives a dilithio derivative, which has been converted to dimethyl 7 or mono-SiMe38 or -Au(PPh3) 9 complexes. Cu(I) and Ag(I) (MI) adducts (“tweezer” complexes) have been obtained from reactions of 2 with MISCN or [MI(NCMe)4]+. An ES mass spectrometric study of the interactions of 2 with Group 1 cations and with Tl+ is also described; comparative experiments with W(CO)3Cp}2(μ-C8)
