Abstract

A homoleptic metal complex with four tripodal tridentate ligands can have chiral tetrahedral T symmetry. An example of such a complex has been prepared, and the proposed highly symmetric, but chiral structure (see schematic representation, MP=mirror plane, R=NHCH₂ PH) has been confirmed.

Keywords: chelates; chirality; group theory; structure elucidation; tripodal ligands.
