Recent advances in pyrazolato-bridged homo- and heterometallic polynuclear platinum and palladium complexes

Shinnosuke Horiuchi et al.

Summary: Multinuclear transition metal complexes and organometallic complexes with pyrazoles and pyrazolate bridging ligands have attracted considerable attention due to their versatile structures and interesting properties. Recent advances in pyrazolato-bridged homo- and heterometallic polynuclear platinum and palladium complexes have highlighted the significance of substituent groups on the pyrazoles and pyrazolates in controlling the stereostructures and selective formation of heteropolynuclear complexes. This review focuses on the synthetic, structural, thermodynamic, electronic, and photophysical properties of Pt- and Pd-based heteropolynuclear complexes.

Heteropolymetallic Architectures as Snapshots of Transmetallation Processes at Different Degrees of Transfer

David Campillo et al.

Summary: Novel heteropolymetallic architectures integrating Pd, Au, and Ag systems have been successfully constructed, and corresponding complexes have been synthesized. The interactions between one of the aryl groups in the CNC ligand and the M-G11 center have been characterized, and the degree of transfer has been qualitatively ordered. The research results offer potentially useful insights for the design of bimetallic catalytic systems.

Model Compounds for Intermediates and Transition States in Sonogashira and Negishi Coupling: d8-d10 Bonds in Large Heterobimetallic Complexes Are Weaker than Computational Chemistry Predicts

Raphael J. Oeschger et al.

Summary: We report an experimental study on a series of heterobimetallic complexes with Pd(II) and Cu(I), Ag(I), or Au(I), accompanied by DFT calculations. The isolable pincer complexes are models for the intermediates and transition state in Sonogashira and Negishi coupling reactions. According to the DFT calculations, only the transition state has the metal centers within bonding distance. We also report a substituted version of a similar heterobimetallic complex, in which competing dissociation limits the strength of the metal-metal bond. Analysis of the structures in different states and the gas phase dissociation experiment suggest that the dispersion-corrected DFT method overestimates the strength of the metal-metal interaction, distorting the computed potential energy surface for transmetalation.

Bimetallic Organoplatinum(II)-Ag(I) Cluster Cations with Ag-Pt Interactions Unsupported by Conventional Bridging Ligands

William Raven et al.

Summary: A mixed-metal complex containing platinum and silver has been characterized using X-ray diffraction, revealing alternating arrangements of silver and platinum without conventional bridging. Short interactions between silver and platinum, as well as contact between silver and carbon atoms in aromatic rings, have been observed.

Rational Synthesis of an Unsymmetric Pt Complex Unit Having Two Kinds of Pyrazolate Ligands: Elucidating Steric and Electronic Effects of Pyrazolate Ligands in Pt-Ag Sandwich Complexes

Shinnosuke Horiuchi et al.

Summary: In this study, a rational synthesis of an unsymmetric Pt complex with two different pyrazole ligands was successfully carried out. The unsymmetric Pt complex was used to selectively form a Z-shaped Pt2Ag2 complex, whose structures were confirmed by X-ray crystallographic and NMR analysis. It was found that the steric effect of the pyrazole ligands determined the orientation of the Pt complex units, but had little influence on the photophysical properties of the complexes. TD-DFT calculations supported the small electronic contributions of the pyrazole moieties in the Pt and Pt2Ag2 complexes. This synthetic route offers a new strategy for obtaining new types of precious metal sandwich complexes.

David Campillo et al.

Summary: Novel heteropolymetallic architectures consisting of Pd, Au, and Ag systems have been constructed, with Au promoting the highest degree of transfer and Pd systems favoring higher degrees. The results provide potentially useful ideas for the design of bimetallic catalytic systems.

A Heteropolynuclear Pt-Ag System Having Cycloplatinated Rollover Bipyridyl Units

Shinnosuke Horiuchi et al.

Summary: The synthesis and photophysical properties of the heteropolynuclear Pt-Ag complex with cyclometalated rollover bipyridine ligands and bridging pyrazolato ligands were reported. The Pt2Ag2 complex exists as a mixture of U- and Z-shaped isomers, with the ability to form Pt. Ag dative bonds and significantly change emission energy. The additional Ag(I) ion affects the photophysical properties of these complexes as revealed by DFT and TD-DFT calculations.

Vibrational Signature of Metallophilic Interactions in [Pt(terpy)Cl][Au(CN)2]

Kasidet Jing Trerayapiwat et al.

Summary: Metallophilic interactions have been utilized to create unique nanostructures with anisotropy of electronic properties. The strength of the interaction is crucial for design. By using angle-resolved Raman spectroscopy, the vibrational signature associated with the Pt-Au interaction in double salt wire was identified.

Reactions of Cycloplatinated Guanidine Complexes with Hg(OC(O)CF3)2: Formation of a One-Dimensional Coordination Polymer Containing a Pt2Hg(μ2-S(O)Me2-S,O) Repeating Unit versus a Discrete Pt2Hg2 Complex

Vishwesh Mishra et al.

Summary: By reacting with Hg(OC(O)CF3)(2), separate reactions of cycloplatinated 2-tolyl- and 2-anisylguanidine complexes yielded a one-dimensional coordination polymer and a discrete tetrametallic complex with different structures and properties. The formation mechanisms and structural characteristics of these products were explained in detail, with important characterization information provided by multinuclear NMR spectroscopy and single-crystal X-ray diffraction studies.
