Structural Report for Sc[(R,R)-norephedrine-pybox](OTf)3 Dimeric Complex

Original Paper

Abstract

The title compound containing two metal centers each complexes to one enantiopure chiral norephedrine-derived pyridyl-(bis) oxazoline (pybox) ligand and linked by two hydroxide bridges, crystallizes to give rodlike form in the space group P21(# 4). Cell Parameters are a = 10.2344(18) Å, b = 13.952(3) Å, c = 23.371(4) Å, β = 94.586(4)°, V = 3326.6(10) Å3. The metal-hydroxide motif forms a square plane at the center of the structure with the scandium centers exhibiting a distorted pentagonal bipyramid coordination sphere consisting of the chelating ligand and two additional triflouromethyl sulfonyloxy species positioned anti to each other.
