A C3-symmetric chiral hexadentate podand ligand based on a tris(pyrazolyl)borate core

Abstract

A hexadentate podand ligand having C3 symmetry has been prepared, consisting of a tris(pyrazolyl)borate core bearing pinene-functionalised 2-pyridyl units attached to the C3 position of each pyrazolyl ring such that each arm is a chiral bidentate chelate; complexes with Tl(I) and Tb(III) have been prepared and structurally characterised.
