Vibrational and electronic structure of the dinuclear bis(µ-nitrido) vanadium(v) complex [V(N{N″}2)(µ-N)]2: spectroscopic properties of the M2(µ-N)2diamond core†
Abstract
The vibrational and electronic structure of the bis-µ-nitrido bridged complex [V(N{N″}2)(µ-N)]2
(1)
(where [N{N″}2]2−
=
[(Me3Si)N{CH2CH2N(SiMe3)}2]2−) is analyzed. Assignment of the five modes of the V2(µ-N)2 core is based on 15N 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 V2(µ-N)2 core are found in the
