Synthesis, molecular and electronic structures of a paramagnetic trimetallic cluster containing an unusual Mo3(μ3-Se)2(μ-Se)3 core

Conversion of the electron precise MoIV3Se4 unit to the paramagnetic MoIV2MoIIISe5 core is achieved upon reduction with gallium, while for the analogous sulfur system a one electron reduction of the Mo3S4 complex is observed.
