Abstract:
A nitrogen-based analogue of the Schrock and Clark "yl-ene-yne" complex, W(CBu )(CHBu )(CH2Bu )(dmpe), has been prepared. The new complex is the nitrido, imido, amido anion [NCr(NPh)(NPri2)2]-, which was structurally characterized with the [K(crypt-2.2.2)]+ counterion. The "Cr-N 1-2-3" complex was prepared from NCr(NHPh)(NPri2)2, which exists as this nitrido-amido tautomer, rather than the bis(imido) Cr(NH)(NPh)(NPri2)2. By selection of electrophile, the nitrido-imido salt K[NCr(NPh)(NPri2)2] can undergo reaction at either the imido or the nitrido to form unusual examples of nitrido or bis(imido) complexes.

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...

Rate-Determining Steps
In a multistep reaction mechanism, one of the elementary steps progresses significantly slower than the others. This slowest step is called the rate-limiting step (or rate-determining step). A reaction cannot proceed faster than its slowest step, and hence, the rate-determining step limits the overall reaction rate.
The concept of rate-determining step can be understood from the analogy of a 4-lane freeway with a short-stretch of traffic-bottleneck caused due to...
