Di- and multinuclear metal cooperation plays a pivotal role in small-molecule activation and functionalization. Herein, we report a symmetric phenoxide-bridged ligand that supports an unsymmetric dititanium dinitrogen complex featuring side-on/end-on N2 coordination. This complex possessed a strongly nucleophilic (N2)4- moiety that readily underwent diverse derivatizations to construct N-C, N-Si, and N-P bonds. Particularly noteworthy are the complex's reactivities with α,ω-dihaloalkanes, which selectively generate structurally distinct N-heterocyclic compounds, showing the potential in constructing diverse N-contained heterocycles directly from N2.

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...

Conformation
The simplest example of a diene is 1,3-butadiene, an acyclic conjugated π system. At room temperature, the molecule exists as a mixture of s-cis and s-trans conformers by virtue of rotation around the carbon–carbon single bond. Although the s-trans isomer is more stable,...
