Abstract

Discovered in a molten polythiophosphate salt reaction, the compound α-Na₆Pb₃(PS₄)₄ is a salt containing the molecular cluster [Pb₃(PS₄)₄].^6- The C_3v symmetry and the saucer shape of this cluster enable columnar stacking along the c-axis. Interestingly, fast cooling of a melt of the stoichiometric composition "Na₆Pb₃(PS₄)₄" results in the putative high-pressure from β-Na₆Pb₃(PS₄)₄ in which the molecular clusters have essentially polymerized through intercluster Pb-S bonding. β-Na₆Pb₃(PS₄)₄ converts slowly (depolymerizes) to the α-form upon annealing below the melting point.
