The vibrational and electronic structure of the bis(mu-nitrido) bridged complex [V(N{N"}2)(mu-N)]2 (1) (where [N{N"}2](2-)=[(Me3Si)N{CH(2)CH(2)N(SiMe3)}2](2-)) is analyzed. Assignment of the five modes of the V(2)(mu-N)2 core is based on (15)N isotope shifts and a DFT calculation on the calculated structure I which is an exact reproduction of 1. The three Raman active modes of the planar V(2)(mu-N)2 core are found in the Raman spectrum whereas the two IR allowed vibrations are identified in the infrared spectrum. Furthermore, the electronic structure of is described which complements earlier theoretical studies on the reaction pathway leading to 1(V. M. E. Bates, G. K. B. Clentsmith, F. G. N. Cloke, J. C. Green, H. D. L. Jenkin, Chem. Commun., 2000, 927). Based on the MO scheme of I the UV-vis transitions of 1 are assigned. 相似文献

This review covers the coordination and general chemistry of the 1,2,3,4,5-penta-arylcyclopentadiene system, as anion, C5Ar5?, radical, C5Ar5, and cation, C5Ar5+, as well as the neutral diene, C5Ar5H, and its derivatives. The structural rigidity and steric saturation offered by the penta-arylcyclopentadienyl ligand give rise to definite structural and geometric properties in its complexes that distinguish its chemistry from that of the parent cyclopentadiene. 相似文献
