The shortest metal‐metal bond

The Chemical Record, 2010
AbstractThe synthesis and isolation of stable bimetallic complexes that contain formally quintuply bonded transition metals is a novel and emerging field of science. Efforts have been undertaken in designing and tuning the ligands to achieve a very short (actually the shortest) metal‐metal bond.

Background of metal-on-metal resurfacing

Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 2006
Hip resurfacing is not a new concept and attempts to treat hip arthritis without resecting the femoral head and neck have been made since the 1950s. The resurgence of new and better-engineered metal-on-metal bearings has provided the means to develop a viable prosthetic solution from a concept that was once abandoned.

Metal allergy and second‐generation metal‐on‐metal arthroplasties

Contact Dermatitis, 2011
There are concerns about the induction of metal allergy with second‐generation metal‐on‐metal prostheses, and the role that this may play in the development of complications such as ‘pseudotumours’ or failure of the implant. In this review, we attempt to set out the current knowledge on this subject. From a review of the literature, it is apparent that

Metal molecules, metal clusters and metal bumps

Journal of Vacuum Science and Technology, 1981
We show that metal clusters manifest a large variety of interesting spectroscopic properties ranging from such phenomena as the extremely long vibrational lifetimes of transition metal dimers, to the extreme fluxionality of form of certain metal trimers to collective electronic oscillations (surface plasmons) in larger clusters which have achieved a ...

Metal–metal and metal–halogen bond cleavage by lanthanide and related metals

J. Chem. Soc., Chem. Commun., 1973
Finely-divided lanthanide and other metals react with substrates such as Mn(CO)5Br, h3–C3H5Fe(CO)3I,[h5–C5H5Mo(CO)3]2, and h5–C5H5Cr(CO)3HgCI in THF to yield reactive solutions which can be utilized as reagents for the synthesis of various organometallic compounds.

Reactivity of Metal-Metal Bonds

Journal of Organometallic Chemistry, 1972
Abstract The reactivity of Me 3 SnMn(CO) 5 , (CH 2 CHCH 2 ) 3 SnMn(CO) 5 , Me 3 SnFeCp(CO) 2 , and Me 2 Sn[FeCp(CO) 2 ] 2 has been investigated with respect to iodine, organomercury chlorides, trialkyl- and triarylchlorosilane, inorganic chlorides (SiCl 4 , SnCl 4 , TiCl 4 , ZnCl 2 , HgCl 2 ) and Mn 2 (CO) l0 .

Assessing the Strength of Metal–Metal Interactions

Inorganic Chemistry, 2019
A proper comparison between bond strengths of different atom pairs is relevant only for the same formal bond order (BO) of atomic interactions, e.g., for single bonds, because it is clear that the higher is the BO or the number of the electron pairs responsible of bonding, the stronger is the bond. For the metal-metal interactions, such a comparison of

Metal-on-metal

The Bone & Joint Journal, 2013
Metal-on-metal bearing related issues in hip replacement and resurfacing continue to generate discussion, concern, audit and research as there are still many unknowns and clarity is required regarding the future implantation of such devices and the follow-up and investigation of patients with metal-
