Abstract

The intramolecular radical–Gd antiferromagnetic coupling (2J1/kB = −11.6 K) is notably strong, as expected from our molecular design, and the intermolecular exchange coupling along the Gd–O–H⋯O–Gd bridges is unexpectedly ferromagnetic with the largest Gd⋯Gd coupling ever known (2J2/kB = +0.12 K).
