  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 complexes [Pt(terpy)L′]n+(terpy = 2,2′:6′,2″-terpyridine; L′= Cl, Br, I, N3 or SCN–, n= 1; L′= NH3, n= 2) have been prepared and their spectroscopic and emission properties studied. Absorption bands are found at 300–350 and at 370–450 nm, which are assigned to the intraligand and metal-to-ligand change-transfer (m.l.c.t.) transitions, respectively.
