Vanadium nitride linear chain polymers and monomers. Synthesis and structures of [V(.mu.-N)Cl2(py)2].infin. and V(N)Cl2(quin)2

Magnetic assemblies based on Mn(III) salen analogues

“…13), where bond distances of Mn N and N Mn* are 1.520(3) and 2.528(3)Å, respectively [83]. Such polymeric nitrido-metal complexes have been observed for V, Mo, W, and Re [84][85][86][87][88]. However, this is the first report of the 1D chain form of Mn(V) N. The nitrido-Mn(V) complexes are diamagnetic due to the formation of frontier orbitals between d-orbitals of Mn(V) ion and p-orbitals of nitrogen [29,31,89].…”

Photo-activation of d0 niobium imido azides: en route to nitrido complexes

“…In a few occurrences, vanadium nitrido species were obtained from high valent trimethylsilyl imido derivatives on reaction with bases or fluorinated reagents which promote the rupture of the imido N-Si bond. [28][29][30] The concomitant formation of strong MRN and Si-X (X = Cl, F) bonds is the driving force for these reactions. Yet, to the best of our knowledge, such transformations have not been observed with Nb and Ta.…”

Dinitrogen binding at vanadium in a tris(alkoxide) ligand environment

“…2 and S11, ESIw) is noteworthy because it provides one of the first examples of a terminal vanadium-nitrido species with noncoordinating cations. 23,24 DFT calculations were performed on a model of 3 to gain insight into the electronic structure of a linearly coordinated dinitrogen ligand by two vanadium centres. Model 3 0 replaces the two t Bu groups in ditox with Me groups for the benefit of simplifying the computation.…”
