The analysis of organometallic compounds with mass spectrometry has some special features in comparison with organic and bioorganic compounds. The first step is the choice of a suitable ionization technique, where the electrospray ionization is certainly the best possibility for most classes of organometallic compounds and metal complexes. Some ionization mechanisms of organometallic compounds are comparable to organic molecules, such as protonation/deprotonation, and adduct formation with sodium or potassium ions; however, in many cases, different mechanisms and their combinations complicate the spectra interpretation. Organometallics frequently undergo various types of adduct and polymerization reactions that result in significantly higher masses observed in the spectra in comparison to molecular weights of studied compounds. Metal elements typically have more natural isotopes than common organic elements, which cause characteristic wide distributions of isotopic peaks; for example, tin has ten natural isotopes. The isotopic pattern can be used for the identification of the type and number of metal elements in particular ions. The ionization and fragmentation behavior also depend on the type of metal atom; therefore, our discussion of mass spectra interpretation is divided according to the different type of organometallic compounds. Among various types of mass spectrometers available on the market, trap-based analyzers (linear or spherical ion-traps, Orbitrap) are suitable to study complex fragmentation pathways of organometallic ions and their adducts, whereas high-resolution and high-mass accuracy analyzers (time-of-flight-based analyzers, or Fourier transform-based analyzers-Orbitrap or ion cyclotron resonance mass spectrometers) provide accurate masses applicable for the determination of the elemental composition of individual ions.

“…Robust, and ideally modular, synthetic methodologies that permit ready assembly of metal-containing compounds and complexes would allow facile exploration of the chemical, physical, and optoelectronic features provided by metal complexes and design of new materials. Such modular methodologies for the construction of large heterometallic complexes which take advantage of the multiple coordination sites offered by ethynyl bipyridines was previously pursued by Lang in his “Tinkertoy” approach. − We have been recently focused on an allied approach to the construction of bimetallic complexes through the preparation of modular organometallic “coordinating tectons”. − A series of bimetallic complexes of the well-studied bifunctional ligand 5-ethynyl-2,2′-bipyridine were synthesized by this approach, and weak electronic communication was observed between two metal centers across this ligand . Indeed, the electronic interactions between metal termini separated by an organic functionality, M–bridge–M′, are often investigated in order to define the intramolecular electron transfer (or wirelike) characteristics of the assembly. − Investigations of organometallic complexes in this area have focused on the mixed-valence characteristics of bimetallic complexes derived from bridging moieties such as polyynes, − oligo(phenylene)ethynylenes, and bis(terpyridine)metal complexes .…”

4-Ethynyl-2,2'-bipyridyl substituted ruthenium alkynyl complexes have been prepared and used to access a range of binuclear homo-metallic ruthenium and hetero-metallic ruthenium-rhenium complexes. These have been characterized by a variety of spectroscopic and single-crystal X-ray diffraction experiments. The IR spectra of a number of these ruthenium alkynyls display multiple ν(C≡C) bands in the IR spectra, which are rationalized in terms of putative conformational isomers, whose calculated infrared stretching frequencies are comparable to those obtained experimentally. The mononuclear alkynyl complexes Ru(C≡C) undergo reversible one electron oxidations centered largely on the alkynyl ligands as inferred from the significant shift in ν(C≡C) frequency on oxidation, whilst the binuclear complex [Ru{C≡C-4bpy-κ 2-N,N'-RuClCp}(dppe)Cp*] + undergoes initial oxidation at the very electron rich {RuCl(bpy)Cp} fragment causing only a small change in ν(C≡C). A combination of IR and UV-vis spectroelectrochemical experiments, supported by quantum chemical calculations on a selected range of conformers, led to the classification of [Ru{C≡C-4-bpy-κ 2-N,N'-RuClCp}(dppe)Cp*] + as a weakly Class II mixed valence compound (H ab = 306 cm-1). These results indicate that there is improved electronic communication through the 4-ethynyl-2,2'-bipyridyl ligand compared to the analogous 5-ethynyl-2,2'-bipyridyl complexes (H ab = 17 cm-1).

“…This can be achieved through the protection and deprotection of donor groups, but an attractive, more synthetically straightforward option is to tailor bifunctional linkers to the metals involved. This approach has been employed by us 7 and others 8 to prepare molecular assemblies consisting of 2-6 metals, including compounds with six different metals. 9 Due to our interest in 1,1'-dithio ligands, 10 our previous contributions have mainly focused on sulfur ligands and these have proved exceptionally useful in the construction of both molecular and nanoparticle systems.…”
