The acid-mediated isomerization of iridium(iii) complexes with cyclometalated NHC ligands: kinetic vs. thermodynamic control

Kay Severin, Farzaneh Fadaei Tirani, Anastasia Gitlina

The isomerization of iridium(III) complexes with metalated N-heterocyclic carbene (NHC) ligands was studied. The fac isomers of complexes with 1-phenyl-3-methylbenzimidazolin-2-ylidene or 1-phenyl-3-benzylbenzimidazolin-2-ylidene ligands are transformed cl ...

Multiple Surface Site Three-Dimensional Structure Determination of a Supported Molecular Catalyst

Moreno Lelli, Pierrick Berruyer, David Benjamin Roger Antoine Gajan, Zhuoran Wang

The structural characterization of supported molecular catalysts is challenging due to the low density of active sites and the presence of several organic/organometallic surface groups resulting from the often complex surface chemistry associated with supp ...

Luminescent Ir(C^N)3 complexes (C^N = cyclometalated arylpyridine ligand) exist in the form of two stable isomers with distinct photophysical and electrochemical properties: fac and mer. Herein, we show that fac-Ir(C^N)3 complexes can be converted into the ...

Versatile coordination of acetazolamide to ruthenium(ii) p-cymene complexes and preliminary cytotoxicity studies

Paul Joseph Dyson, Lucinda Kate Batchelor

The carbonic anhydrase inhibitor acetazolamide (AcmH2) reacted with [(η6-p-cymene)RuCl(μ-Cl)]2 to afford [(η6-p-cymene)RuCl2(κN-AcmH2)], 1A, in near-quantitative yield. In methanol, 1A exists in equilibrium with 1B, being probably a coordination isomer, as ...

Synthesis, structural determination, theoretical studies and catalytic activity of Mn(II) complex of N-isonicotinyl phosphoric triamide ligand

Kurt Schenk, Farzaneh Fadaei Tirani

synthesized and characterized by H-1, C-13, P-31 NMR and IR spectroscopies. The reaction of MnCl2 center dot 4H(2)O with L led to the formation of a new 3D system {MnL2Cl2}(n)center dot 34CH(3)OH (C-1). X-ray crystallographic data revealed that the ligand ...

Cationic Iridium(III) Complexes with Two Carbene-Based Cyclometalating Ligands: Cis Versus Trans Isomers

Michael Graetzel, Mohammad Khaja Nazeeruddin, Rosario Scopelliti

A series of cationic iridium(III) complexes with two carbene-based cyclometalating ligands and five different NN bipyridine and 1,10-phenanthroline ancillary ligands is presented. For the first time in the frame of a rarely studied class of bis(heterole ...

Microhydration Effects on the Encapsulation of Potassium Ion by Dibenzo-18-Crown-6

Thomas Rizzo, Yoshiya Inokuchi

We have measured electronic and conformer-specific vibrational spectra of hydrated dibenzo-18-crown-6 (DB18C6) complexes with potassium ion, K+center dot DB18C6 center dot(H2O)(n) (n = 1-5), in a cold, 22-pole ion trap. We also present for comparison spect ...
