In this study, we examine several reduced ternary molybdates in the family of rare earth molybdenum bronzes produced by electrochemical synthesis with composition LnMo16O44. These compounds contain an array of electrically isolated but magnetically interacting multi-atom clusters. These arrayed “pseudoatom” clusters are shown to support a single hole shared among eight molybdenum atoms in the unit, corresponding to a net spin moment of 1μB, and exhibit a unique magnetic exchange between the units. The findings presented here expand on the physics of the unusual collective properties of multi-atom clusters and extend the discussion of such assemblages to the rich structural chemistry of molybdenum bronzes.
