A hexadentate podand ligand having C-3 symmetry has been prepared, consisti
ng of a tris(pyrazolyl)borate core bearing pinene-functionalised 2-pyridyl
units attached to the C-3 position of each pyrazolyl ring such that each ar
m is a chiral bidentate chelate; complexes with Tl(I) and Tb(III) have been
prepared and structurally characterised.
