The construction of longer chains of sp-hybridized atoms, while relatively facile for carbon, is essentially unknown in the absence of carbon. Our recent results with the 1,3-haloboration of the [WNN] fragment of a Chatt-type complex are herein utilized in the synthesis of homo- and heterobimetallic complexes spanned by long all-inorganic sp chains. Notably, this includes structural confirmation of the longest sp-hybridized inorganic chain ever constructed, in a bimetallic complex with a six-atom all-sp {NNBBNN} bridging ligand.

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...
