Since the discovery of a formal quintuple bond in Ar'CrCrAr' (CrCr = 1.835 A) by Power and co-workers in 2005, many efforts have been dedicated to isolating dichromium species featuring quintuple-bond character. In the present study we investigate the electronic configuration of several, recently synthesized dichromium species with ligands using nitrogen to coordinate the metal centers. The bimetallic bond distances of Power's compound and Cr(2)-diazadiene (1) (CrCr = 1.803 A) are compared to… Expand

Pushing the Limits of Delta Bonding in Metal-Chromium Complexes with Redox Changes and Metal Swapping.
Into the metalloligand Cr[N(o-(NCH2P((i)Pr)2)C6H4)3] (1, CrL) was inserted a second chromium atom to generate the dichromium complex Cr2L (2), which is a homobimetallic analogue of the known MCrLExpand
The ligand-based quintuple bond-shortening concept and some of its limitations.
The ligand-based concept of shortening quintuple bonds and some of its limitations are reported and a chromium-arene sandwich complex structurally related to the classic dibenzene chromium complex was observed, even when bulkier substituents are introduced at the central carbon atom of the used guanidinato ligand.

M5M – Key compounds of the research field metal–metal quintuple bonding
Abstract Since, the isolation of the first stable formally quintuple bonded chromium dimer Ar′CrCrAr′ (Ar′ = 2,6-(2,6-iPr2C6H3)2C6H3) in 2005 by Power and coworkers, the chemistry of high bond orderExpand
Exploring chromium(III)-alkyl bond homolysis with CpCr[(ArNCMe)2CH](R) complexes.
A range of paramagnetic Cr(III) monohydrocarbyl complexes CpCr[(ArNCMe)2CH](R) were synthesized to investigate how varying the steric and electronic properties of the R group affected their propensity for Cr-R bond homolysis. Expand
Assessing metal-metal multiple bonds in Cr-Cr, Mo-Mo, and W-W compounds and a hypothetical U-U compound: a quantum chemical study comparing DFT and multireference methods.
To gain insights into the trends in metal-metal multiple bonding among the Group 6 elements, density functional theory has been employed in combination with multiconfigurational methods (CASSCF andExpand
Synthesis and redox reactivity of a phosphine-ligated dichromium paddlewheel
Abstract A pentadentate ligand platform, bis[2-(diisopropylphosphino-methylamino)phenyl]ether ( 1 ), abbreviated as H 2 (PNONP), is introduced that enables the isolation of homodinuclear chromiumExpand
Computational insights into uranium complexes supported by redox-active α-diimine ligands.
Results from these studies have established that both uranium centers are tetravalent, that the ligands are reduced by two electrons, and that the ground states of these molecules are triplets. Expand
Terphenyl complexes of molybdenum and tungsten with quadruple metal-metal bonds and bridging carboxylate ligands.
In M2(Ar')2(O2CR)2 complexes the two metal atoms have formally a low coordination number and an also low electron count, however, the unsaturation seems to be compensated by a weak M-C(arene) bonding interaction that implicates one of the aryl substituents of the terphenyl central aries ring.

Heterobimetallic Complexes That Bond Vanadium to Iron, Cobalt, and Nickel.
Zero-valent iron, cobalt, and nickel were installed into the metalloligand V, generating the heterobimetallic trio FeVL (2), CoVL (3), and NiVL (4), respectively, which have short M-V bond lengths that are consistent with M-M multiple bonding. Expand
