Abstract
In spite of the short Nb−Nb distance (2.268 Å) and the presumable existence of an Nb≡Nb bond, the paddle-wheel-shaped diniobium(II) complex 1 is paramagnetic. Theoretical calculations indicate that the presence of LiCl moieties on the intermetallic axis lowers the Nb−Nb bond order and is responsible for the observed paramagnetism.This publication has 0 references indexed in Scilit:
