  Metal–metal stacking patterns between and with [Pt(tpy)X]+ cations

  摘要：

  A comparative study of metallophilic interactions of [Pt(tpy)X](+) cations (tpy = 2,2': 6',2 ''-terpyridine) in the presence of two different types of anions, (i) [AuX2'] anions that form double salts and (ii) simple p-block anions, is reported. Single-crystal X-ray diffraction data, solution-state Pt-195 NMR spectra, and variable temperature solid-state luminescence spectra are reported. Three [Pt(tpy)Cl]Y derivatives (Y = SbF6, 1, SbF6 center dot CH3CN, 4, PF6, 2) and the [Pt(tpy)Br]PF6 analog, 3, as well as two new double salts [Pt(tpy)CN][Au(CN)(2)], 5, and [Pt(tpy)CN](2)[Au(C6F5)(2)](PF6), 6, have been synthesized and characterized. Structural analysis shows consistent patterns in Pt center dot center dot center dot Pt interactions that vary slightly depending on the coordinating halogen or pseudo-halogen X, counter anion Y, and lattice solvent. Metallophilic interactions are seen between [Pt(tpy)X](+) cations with all types of X ligands, but only with pi-accepting X' ligands from [AuX2'] anions are Pt center dot center dot center dot Au metallophilic interactions seen to be favored over Pt center dot center dot center dot Pt interactions. The [Au(CN)(2)] anion consistently forms Pt center dot center dot center dot Au metallophilic contacts, unlike [Au(C6F5)(2)] . The Pt-195 NMR chemical shifts are similar to-2750 ppm for pi-donor ligands and near -3120 ppm for pi-acceptor ligands in [Pt(tpy)X]PF6 compounds. Luminescence data show an unusual blue shift in [Pt(tpy)CCPh][Au(C6F5)(2)] versus [Pt(tpy)CCPh]PF6 ascribed to an intermolecular charge transfer. (C) 2010 Elsevier B.V. All rights reserved.

  The crystal structure of [Pt(trpy)(MeCN)](SbF6)(2), where trpy denotes 2,2':6',2 ''-terpyridine, shows that the platinum complex packs as a monomer; however, the (3) pi-pi emission of the solid occur at surprisingly long wavelengths at room temperature. At lower temperatures new, shorter-wavelength maxima appear. Of the known sails with the composition [Pt(trpy)Cl]A, the A = SbF6- system is the lone example that exhibits a temperature-independent emission maximum. In these platinum(II) terpyridines, energy migration to defects or trap sites is one of the phenomena responsible for the temperature dependence of the solid-state emission spectrum. IT trap emission is evident, the low-temperature spectral data are most representative of the bulk material.

  The synthesis a and characterisation of an orange polymorph of [Pt(trpy)(C CPh)]SbF6 is described where trpy = 2,2':6',2 ''-terpyridine. An X-ray crystal structure determination at 293 K reveals that the cations are planar and stacked head-to-tail with alternating Pt center dot center dot center dot Pt distances of 3.604(l) and 4.412(l) angstrom. The perpendicular distances between successive cation planes are constant along the stack at a value of 3.33 angstrom. Crystal structure determinations at 240 and 200 K show that reducing the temperature to 200 K has no significant effect on the cation arrangement, However, below 200 K there is a phase change that we have not been able to characterise, but which has an effect on the solid state photoluminescence exhibited by [Pt(trpy)(C CPh)]SbF6. Thus, whereas at temperatures of >= 200 K, a broad peak with two components at ca. 566 and 597 nm is observed, below 200 K a longer wavelength peak develops that red-shifts as the temperature is lowered [lambda(em)(max) = 637 nm at 80 K]. We assign the >= 200 K emission as (MLLCT)-M-3 in origin, since the X-ray data show that ligand-ligand (LL) and not metal metal (MM) interactions are important at T >= 200 K. On the other hand, the long wavelength emission observed below 200 K is typical of (MMLCT)-M-3 emission, suggesting that the phase change leads to d(z2) (Pt)-d(z2) (Pt) orbital interactions. Of particular interest is that the cation exhibits (MLCT)-M-3 emission in dichloromethane that maximizes at 619 nm, i.e., the high temperature solid state emission occurs at a shorter wavelength, an unexpected result since intermolecular interactions in the solid usually cause the emission to occur at longer wavelengths. A possible explanation for this unexpected result is given. (c) 2006 Elsevier B.V. All rights reserved.
