Hydroxo Radicals, C–H Activation, and Pt–C Bond Formation from 77 K Photolysis of a Platinum(IV) Hydroxo Complex

24.10.2014 | Lasantha A. Wickramasinghe; Paul R. Sharp, Inorganic Chemistry, 2014

Photolysis (380 nm) of trans,cis-Pt(PEt3)2(Cl)2(OH)(4-tft) (4-tft = 4-trifluoromethylphenyl) at 77 K in 2-methyltetrahydrofuran gives triplet emission, platinum(III), and a hydroxo radical. Benzyl radical emission is observed in toluene from the reaction of a portion of the OH radicals with ...

Intermolecular Interactions in Solid-State Metalloporphyrins and Their Impacts on Crystal and Molecular Structures

23.10.2014 | Seth C. Hunter; Brenda A. Smith; Christina M. Hoffmann; Xiaoping Wang; Yu-Sheng Chen; Garry J. McIntyre; Zi-Ling Xue, Inorganic Chemistry, 2014

A variable-temperature (VT) crystal structure study of [Fe(TPP)Cl] (TPP2– = meso-tetraphenylporphyrinate) and Hirshfeld surface analyses of its structures and previously reported structures of [M(TPP)(NO)] (M = Fe, Co) reveal that intermolecular interactions are a significant factor in structure ...

Continuous Control of Optical Gaps in Quasi-One-Dimensional Bromide-Bridged Platinum Complexes by Utilizing Chemical Pressure

23.10.2014 | Shohei Kumagai; Hiroaki Iguchi; Shinya Takaishi; Brian K. Breedlove; Masahiro Yamashita; Hiroyuki Matsuzaki; Hiroshi ..., Inorganic Chemistry, 2014

The optical gap in a series of bromo-bridged platinum chain complexes, [Pt(en)2Br](Cn–Y)2·H2O (en = ethylenediamine; Cn–Y = dialkyl sulfosuccinate; n = the number of carbon atoms), was controlled by using chemical pressure. From the single-crystal structure, [Pt(en)2Br](C6–Y)2·H2O is in a ...

Local Supersaturation Dictated Branching and Faceting of Submicrometer PbS Particles with Cubic Growth Habit

23.10.2014 | Mingzhu Liu; Mei Leng; Dan Liu; Fanglin Chen; Chengyu Li; Cheng Wang, Inorganic Chemistry, 2014

Hierarchical cubelike submicrometer PbS particles consisting of truncated octahedrons, cuboctahedrons, and cubes were prepared in ethylene glycol solution under favorable high mole ratio of thiourea (Tu) to Pb(AC)2 (RS/Pb) via a pumping process. A qualitative analysis based on the classical ...

A First-Principles Approach to the Calculation of the on-Site Zero-Field Splitting in Polynuclear Transition Metal Complexes

23.10.2014 | Marius Retegan; Nicholas Cox; Dimitrios A. Pantazis; Frank Neese, Inorganic Chemistry, 2014

The interpretation of electron paramagnetic resonance spectra of polynuclear transition metal complexes in terms of individual contributions from each paramagnetic center can be greatly facilitated by the availability of theoretical methods that enable the reliable prediction of local ...

Electrocatalytic Reduction of CO2 with Palladium Bis-N-heterocyclic Carbene Pincer Complexes

22.10.2014 | Jeffrey A. Therrien; Michael O. Wolf; Brian O. Patrick, Inorganic Chemistry, 2014

A series of pyridine- and lutidine-linked bis-N-heterocyclic carbene (NHC) palladium pincer complexes were electrochemically characterized and screened for CO2 reduction capability with 2,2,2-trifluoroethanol, acetic acid, or 2,2,2-trifluoroacetic acid (TFA) as proton sources. The lutidine-linked ...

Mechanically Triggered Fluorescence/Phosphorescence Switching in the Excimers of Planar Trinuclear Copper(I) Pyrazolate Complexes

22.10.2014 | Qiong Xiao; Ji Zheng; Mian Li; Shun-Ze Zhan; Jun-Hao Wang; Dan Li, Inorganic Chemistry, 2014

Luminescence mechanochromism of the well-known Cu3Pz3-type (Pz = pyrazolate) complexes is reported here, which is unusual for this family. Two types of new Cu3Pz3 complexes, namely Cu3(EBPz)3 (1; EBPz = ethyl-4′-benzoate-3,5-dimethylpyrazolate) and Cu3(MBPz)3 (polymorphs 2a–c; MBPz = ...

Structure and Bonding of Bi4Ir: A Difficult-to-Access Bismuth Iridide with a Unique Framework Structure

22.10.2014 | Anna Isaeva; Michael Ruck; Konrad Schäfer; Ute Ch. Rodewald; Rainer Pöttgen, Inorganic Chemistry, 2014

Crystals of Bi4Ir, a new intermetallic compound, were obtained by the reaction of an iridium-containing intermetallic precursor with liquid bismuth. X-ray diffraction on a single crystal revealed a rhombohedral structure [R3̅m, a = 2656.7(2) pm, and c = 701.6(4) pm]. Bi4Ir is not isostructural to ...

X-ray Absorption and Emission Spectroscopies of X-Bridged Diiron Phthalocyanine Complexes (FePc)2X (X = C, N, O) Combined with DFT Study of (FePc)2X and Their High-Valent Diiron Oxo Complexes

22.10.2014 | Cedric Colomban; Evgenij V. Kudrik; Valerie Briois; Janine C. Shwarbrick; Alexander B. Sorokin; Pavel Afanasiev, Inorganic Chemistry, 2014

μ-Nitrido diiron phthalocyanine [PcFe+3.5NFe+3.5Pc]0 is an efficient catalyst, able to catalyze the oxidation of methane under near-ambient conditions. In this work, we compared the properties of structurally similar μ-carbido (1), μ-nitrido (2), and μ-oxo (3) dimers of iron phthalocyanine. The ...
