We find a Cu(II)-() complex ( = 2,2,2-trifluoro--[2-(pyridin-2-yl)propan-2-yl]acetamide) with a distorted "seesaw" geometry. It has the shortest crystallographic CF···Cu distances yet reported, to the best of our knowledge (<2.6 Å), for which computational and experimental data indicate a secondary bonding interaction. A comparison with a CCl version and one without ligand backbone -dimethyl groups suggests a steric origin for the distorted geometry, resulting from the specific ligand interactions.
