Novel co-ordination numbers in scandium(III) and yttrium(III) nitrato-comlplexes. X-ray crystal structures of Sc(NO3)3.2N2O4 and Y(NO3)3.2N2O4
Abstract
X-Ray crystallographic studies of the anions [Sc(NO3)5]2– and [Y(NO3)5]2–, which have been prepared using liquid N2O4, have revealed novel co-ordination numbers of nine for scandium(III) and ten for yttrium(III), with geometries best described in terms of a pseudotrigonal bipyramid.
