We found similar results for ag [TBuA][Fe(dca)3] and ag [TBuA][Co(dca)3] materials (Fig. ). The short-range correlations (A ⃖⃗ -F ⃡ ) present in the glass samples were relatively similar to the crystalline precursors (Fig. , Fig. ). Correlations belonging to Mn-N-C (C ⃡ ) and Mn-N-C-N (D ⃖B⃗ ) were however reduced in intensity and substantially broadened. Prominent correlations were also not observed beyond 10 Å, consistent with the mechanism of melting involving the breakage of M-N bonds, and the associated movement of the A site cation out of the central cavity. Difficulties in preparing a sufficient quantity of finely ground solid samples for PDF measurements of ag [TPnA][Fe(dca)3] and ag [TPnA][Co(dca)3] (owing to their viscous melts), led us to obtain variable temperature PDF data for these two compounds. Data collected in the liquid state for each bore a strong resemblance to those for other glass samples in this study, maintaining the same correlations as preheated material and with a similar behavior to their homologous ag [TPnA][Mn(dca)3] (Fig. ).
