The title compound, has been prepared; its crystal structure, solved at room temperature, consists of dimer units bridged by oxalate lignads. Each copper ion is surrounded by two nitrogens of bromazepam and two oxygens of the oxalate ligand; a molecule of water occupies the apical site. The magnetic properties of the title compound have been investigated in the 30–300 K range. The molar magnetic susceptibility closely follows the behaviour expected for an antiferromagnetically coupled copper(II) binuclear complex with a singlet-triplet energy gap,J=−349 cm−1.
