Transition Metal Carbyne Complexes

Journal of Organometallic Chemistry, 1981
Abstract IR (2200−200 cm−1) and Raman (2200−30 cm−1) spectra of (CO)5ReM(CO)4CC6H5 (M = Cr, Mo, W) and (CO)5ReW(CO)4CCH3 were recorded and interpreted. Polarized Raman spectra obtained with single crystals of some of the compounds permitted the assignment of the vibrational bands for these molecules.

Transition Metal Complexes of Boron

Angewandte Chemie International Edition, 1998
Rapid advances have been made over the past few years in the chemistry of transition metal complexes with σ-bonded boryl and borylene ligands. The use of suitable substituents on boron has made possible both the synthesis and complete characterization of numerous compounds of this type, and the analysis of spectroscopic data provides the first insight ...

Transition metal complex exciplexes

Coordination Chemistry Reviews, 1996
Abstract The photophysical and photochemical properties of exciplexes are summarized considering the electronic structure and role of energetics and kinetics in the formation and stabilization of these molecular entities. Exciplexes involving transition metal complexes, are known as transition metal complex exciplexes (TMCEs) and are classified on ...

Photophysics of Transition Metal Complexes

2011
This report summarises the literature reported in 2010 on the photophysical properties of metal complexes and their polynuclear supramolecular assemblies. The transition metal species considered here have been largely studied because of their optical properties, in particular luminescence.

Transition metal methylene complexes

Journal of Organometallic Chemistry, 1977
Abstract μ-Carbonylbis(carbonyl-ν5-cycopentadienylrhodium)(Rh—Rh) reacts with N-methyl-and N-ethyl-N-nitrosourea in boiling benzene to yield the dinuclear, diamagnetic, neutral rhodium complexes μ-methylene- (A) and μ-ethylidenebis(carbonyl-η5-cyclopentadienylrhodium)(Rh—Rh) (B), respectively.

Transition-metal polyhydride complexes

Coordination Chemistry Reviews, 1985
Abstract Several general conclusions can be drawn from the information now available on polyhydride complexes. Perhaps their most striking property is simply their existence in such great numbers. Their relative stability to loss of H2 seems to be thermodynamic, not simply kinetic, because many synthetic routes involve H2 addition, and H2 addition ...

Transition Metal Nitrosyl Complexes

1989
Publisher Summary In recent years transition metal nitrosyl compounds have attracted considerable interest. This chapter describes the synthesis of transition metal nitrosyl complexes with particular reference to routes that involve common reagents (for example, NO and NOBF4).

Dimetallostannylene-transition-metal complexes

Organometallics, 1990
The crystalline complex [{Fe(CO) 3 (μ-CO)}-(SnFp 2 )]-(O-Sn) (1), [{Cr(CO) 4 (μ-CO)}(SnFp 2 )] 2 -(O,Sn) (2), and [Fe(CO) 4 {SnFp 2 (Py)}] (3) [Fp=Fe(η-C 5 H 5 )(CO) 2 ] have been prepared; X-ray data on 1 and 2 show them to be centrosymmetric dimers by virtue of two isocarbonyl-tin ...

Complex Transition Metal Hydrides

Angewandte Chemie International Edition in English, 1988
AbstractCompounds having structural units formed by transition metals and hydrogen have only become known fairly recently. Only the synthesis and structural characterization of ternary metal hydrides AxMyHz in which A is an alkali or alkaline‐earth metal and M is a transition metal, led to the discovery of anionic complex groups of the form [MHz ...
