Different coordination modes of an aryl-substituted hydrotris(pyrazolyl) borate ligand in rhodium and iridium complexes
(Elsevier, 2011)
Complexes TptolRh(C2H4)2 (1a) and TptolRh(CH2C(Me)C(Me)CH2) (1b) have been prepared by reaction of KTptol with the appropriate [RhCl(olefin)2]2 dimer (Tptol means hydrotris(3-p-tolylpyrazol-1-yl)borate). The two complexes ...

Synthesis and reactivity studies of cationic Ir(III) alkylidines. α-hydride abstraction reactions
(Sociedad Química de México, 2017)
The chemistry of late transition metal alkylidenes [M=CR2], where R is H a hydrocarbyl group, have attracted widespread attention although mainly with reference to complexes of metals in low oxidation state. We focus in ...

Unmasking the constitution and bonding of the proposed lithium nickelate “Li3NiPh3(solv)3”: revealing the hidden C6H4 ligand
(Royal Society of Chemistry, 2022)
More than four decades ago, a complex identified as the planar homoleptic lithium nickelate “Li3NiPh3(solv)3” was reported by Taube and co-workers. This and subsequent reports involving this complex have lain dormant since; ...

Synthesis, properties, and some rhodium, iridium, and platinum complexes of a series of bulky m-terphenylphosphine ligands
(Elsevier, 2016)
A series of sterically demanding aryl phosphine ligands (L) bearing terphenyl substituents, PR2Ar′ (R = hydrocarbyl, Ar′ = 2,6-diarylphenyl radical) has been prepared and characterized. The stability of these ligands towards ...

The dizinc bond as a ligand: A computational study of elongated dizinc bonds
(Elsevier, 2018)
Following the synthesis of [Zn 2 (η 2 -C 5 Me 5 ) 2 ] (in short [Zn 2 Cp ∗ 2 ]) many complexes of the directly bonded Zn-Zn unit were prepared and characterized, leading to the recognition of an isolobal analogy between ...
