  Pyrazolate-bridged group 11 metal(I) complexes: Substituent effects on the supramolecular structures and physicochemical properties

  摘要：

  Polynuclear homoleptic pyrazolate-bridged group 11 metal(I) complexes with three different alkyl substituted pyrazolate anions, 3,5-diisopropylpyrazolate (3,5-iPr(2)pz = L1 ), 3-tert-butyl-5-isopropylpyrazolate (3-tBu-5-iPrpz = L3 ), and 3,5-di-tert-butylpyrazolate (3,5-tBu(2)pz = L4 ), i. e. [Cu(mu-3,5-iPr(2)pz)](3) (CuL1), [Ag(mu-3,5-iPr(2)pz)](3) (AgL1), [Au(mu-3,5-iPr(2)pz)](3) (AuL1), [Cu(mu-3-tBu-5-iPrpz)](4) (CuL3), [Ag(mu-3-tBu-5-iPrpz)](3) (AgL3), [Au(mu-3-tBu-5-iPrpz)](4) (AuL3), [Cu(mu-3,5-tBu(2)pz)](4) (CuL4), [Ag(mu-3,5-tBu(2)pz)](4) (AgL4), and [Cu(mu-3,5-tBu(2)pz)](4) (AuL4), were systematically synthesized in order to investigate the influence of pyrazole bulkiness on their structures and physicochemical properties. The structural characterization indicates that the geometries are greatly influenced by the steric hindrance exerted by the substituent groups of the pyrazolyl rings and the differences of the central metal (I) ionic radius (Cu+ < Au+ < Ag+). These complexes were also characterized by spectroscopic techniques, namely, UV-Vis, IR/far-IR, Raman, and luminescence spectroscopy. (C) 2010 Elsevier B. V. All rights reserved.

  The reaction of Au(tht)Cl and 3,5-Bu-t(2)-pzH (pzH = pyrazole) in the presence of a base gives a tetranuclear complex as its only crystalline product. The latter has been characterized in solution by H-1 and C-13 NMR, as well as in two crystalline forms-[Au(mu-3,5-Bu-t(2)-pz)](4) (1) and [Au(mu-3,5-Bu-t(2)-pz)](4).CH2Cl2, (1.CH2Cl2)-by single crystal X-ray diffraction. Under UV irradiation, both 1 and 1. CHCl2 solid samples, as well as a CH2Cl2 solution of 1 luminesce with lambda(max) 541, 517 and 550-600 nm, respectively. Attempts to oxidize [Au(mu-3,5-Bu-t(2)-pz)](4) by I-2 fail, while oxidation reactions by Br-2 or aqua regia yield AuBr4- and AuCl4-, respectively. (C) 2003 Elsevier Science B.V. All rights reserved.
