Abstract

Long-range antiferromagnetic coupling impeded electron flow through the hexaradical-containing tetranuclear Co^III₄ complex (1), while the nonradical-containing tetranuclear Co^III₄ complex (2), with no paramagnetic centres, was a semiconductor and sensed NH₃ efficiently at room temperature (25 °C).
