A solvothermal reaction of a cupric salt and tetrazole in acetonitrile generates a tetrazolate (tta)- and cyano-bridged homometallic mixed- valence copper(I,II) molecular ferrimagnet, [Cu5(tta)6(CN)2] (see figure), that exhibits a field-induced transition from a 3D antiferromagnetic state to a ferrimagnetic state at 7.9 K.
