  摘要：

  Pt（tpy）X 3+ [X ＝ Cl（1），Br（2）； H ＝ 1。如1934年Morgan和Burstall最初报道的那样，通过Pt（tpy）X +与X2的氧化加成制备tpy = 2,2'：6'，2''-terpyridine]盐。该络合物已通过1H NMR光谱进行了全面表征，元素分析，质谱和X射线晶体学。使用吸收和发射光谱研究了1和2的电子结构，并且所积累的数据与针对1和2的单重配体中心和潜在的单重配体场/单配体到金属的电荷转移态的稳定化相一致与Pt（tpy）Cl +（3）和Pt（tpy）Br +（4）相同。最低能量吸收状态的变化导致1-4之间的发射行为存在巨大差异。具体来说，

  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.
