Abstract

The crystal structures and basic magnetic properties of Prd₄Cr₃Cl₁₂and Prd₄V₃Cl₁₂(Prd = pyrrolidinium, C₄H₁₀N⁺), previously unreported organic–inorganic hybrid compounds, are described. These compounds are synthesized via solid-state methods, and their crystal structures contain face-sharing [M₃Cl₁₂]^4–trimers possessing the configuration M³⁺–M²⁺–M³⁺that are isolated from one another by pyrrolidinium cations. Magnetic analyses reveal that the dominant magnetic correlations for both materials are antiferromagnetic, with particularly strong coupling observed in Prd₄V₃Cl₁₂. Neither compound exhibits long-range magnetic ordering down to 0.8 K, though sharp upturns in heat capacity data may signify the onset of such transitions.
