The field of quadruply bonded dinuclear complexes in which two metal atoms are embraced by eight ligands has been considered mature. The bonding and electronic structures of these compounds have been well understood, ever since the discovery of the first dimetal species containing a quadruple bond, [Re2Cl8] 2 , over 40 years ago. The quest for thermally stable and isolable dinuclear complexes with higher bond orders is one aim of chemists in this field. From the synthetic point of view…

Quintuply-bonded dichromium(I) complexes featuring metal-metal bond lengths of 1.74 A.
TLDR
A series of complexes of the form [Cr2{m-h -ArNC(R)NAr}2], which all exhibit very short Cr Cr quintuple-bond lengths of approximately 1.74, are reported, from which metal–metal quintuple bonds are expected.
Discovering complexes containing a metal-metal quintuple bond: from theory to practice.
TLDR
Recent advances in quintuple bond chemistry are reviewed including the synthesis, characterization and reactivity of quintuple bonded complexes, which show interesting reaction chemistry with unsaturated hydrocarbons and small inorganic molecules.
The ligand-based quintuple bond-shortening concept and some of its limitations.
TLDR
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.
Theory, synthesis and reactivity of quintuple bonded complexes.
TLDR
This perspective reviews recent advances in the newly discovered metal-to-metal quintuple bonded complexes and identifies three types of quintuple bonding complexes that are highly reducing and have been shown to be reactive towards small inorganic molecules and unsaturated organics.
Interconversion of quadruply and quintuply bonded molybdenum complexes by reductive elimination and oxidative addition of dihydrogen.
TLDR
The results demonstrate that quadruply and quintuply bonded dimolybdenum complexes may interconvert by means of reductive elimination and oxidative.
Cycloaddition reactions of a chromium-chromium quintuple bond.
TLDR
This work reports on reactions between a chromium–chromium quintuple bond and substituted acetylenes and dienes, and analogies of quintuple bonds to simple double and triple bonds.
The δ Bond and Trigonal Paddlewheels Before the Dawn of the Quintuple Bond
Recognition five decades ago of the existence of a quadruple bond in the (Science 1964, 145, 1305) brought the δ bond into the toolbox of inorganic chemists. This discovery was followed by an
A Journey of Metal‐metal Bonding beyond Cotton's Quadruple Bonds
Whereas the study of the Cotton's quadruple bonding between two metal atoms has been mature, exploration of bonding, potential applications and reactivity in linear oligonuclear metal complexes and
The shortest metal-metal bond.
TLDR
A chromium homo-bimetallic complex with a Cr-Cr bond length of 1.7293(12) Å has been synthesized, and a formal bond order of five was assigned, and this compound holds the record for the shortest metal-metal bond in a stable molecule to date.
