Conspectus Carbon monoxide, CO, is one of the most important ligands in organometallic
chemistry. It is an excellent π-acceptor and a moderate σ-donor. Therefore, most of the …

To access the hitherto almost unknown class of clustered transition metal carbonyl cations,
the trimetal dodecacarbonyls M3 (CO) 12 (M= Ru, Os) were reacted with the oxidant Ag+ …

Abstract 130 years after Mond discovered the first homoleptic carbonyl complex Ni (CO) 4,
we report on a [Ni (CO) 4].+ salt as the first synthesis of any homoleptic nickel carbonyl …

The reaction of Ag+ with Ru3 (CO) 12 in a CO atmosphere under concommittant irradiation
with UV-light yields a salt of the metal-only Lewis-pair [Ag {Ru (CO) 5} 2]+. Switching the …

Here we present stable and crystalline chromium (I) tetracarbonyl complexes with pyridyl‐
MIC (MIC= mesoionic carbene) ligands and weakly coordinating anions (WCA=[Al (ORF) …

Pairing cations with weakly coordinating anions (WCAs) often renders them highly Lewis‐
acidic and extremely reactive. Although these features are often desirable, excessive …

A selective deelectronation reagent with very high potential of+ 2.00 (solution)/+ 2.41 V
(solid‐state) vs. Fc+/0 and based on a room temperature stable perfluoronaphthalene …

Fluorinated tris (pyrazolyl) borate supporting ligands enable the stabilization of silver (I)
bonded to a neutral, organometallic Fe (CO) 5 ligand. The Ag–Fe interaction in these …

The title silver (I) complex salts [Ag {Re2 (CO) 10}{Re (CO) 5} 2]+[Al (ORF) 4]−(AgRe4; ORF=‐
OC (CF3) 3) and [Ag {Ir4 (CO) 12} 2]+[Al (ORF) 4]−(AgIr8) form upon reaction of Ag+ [Al …

Syntheses of the copper and gold complexes [Cu {Fe (CO) 5} 2][SbF6] and [Au {Fe (CO) 5}
2][HOB {3, 5‐(CF3) 2C6H3} 3] containing the homoleptic carbonyl cations [M {Fe (CO) 5} …
