S atom adopts a pyramidal bridging arrangement. The copper(II) complex represents one of the few known stable alkanethiolate species. Variable-temperature magnetic susceptibility measurements show a small decrease of µCu with decreasing temperature indicative of weak antiferromagnetic exchange coupling. The analogous alcoholate O-bridged complex is much more strongly coupled due, primarily, to the
