A thermally reversible photoinduced magnetic trinuclear complex [Cu2(bpmen)2][MoIV(CN)8]∙8H2O

A trinuclear complex [CuII2(bpmen)2][MoIV(CN)8]∙8H2O was synthesized and structurally characterized, crystallized in the monoclinic system, space group Cc with cell constants a = 11.726(2)Å, b = 17.158(3)Å, c = 23.891(5)Å, β = 97.96(3)° and Z = 4. It exhibited thermally reversible photo-responsive properties on UV light irradiation through a MoIV to CuII charge transfer, which is potential interest for the molecular storage of information as a multifunctional molecule-based material.
