Abstract
The tridentate macrocyclic ligand (MeTRI) derived from the Schiff base condensation of 2-amino-5-methylbenzaldehyde forms a bis complex with copper(II) that exhibits a dynamic Jahn-Teller distortion. The complex crystallizes in the cubic space group Pa3 with a = 16.445 (5) Å at 105 K and Z = 4. The structures were determined at 298 and 105 K. D3 site symmetry at the copper ion is achieved by its coordination to two MeTRI ligands. The immediate coordination sphere of the copper ion consists of six symmetry-equivalent nitrogen atoms (Cu-N = 2.058 (6) Å). Although no phase transition was observed at low temperature, the coordinated nitrogen atoms exhibited the large thermal anisotropies often associated with a dynamic Jahn-Teller distortion.
