Ex-situ, room temperature PDF data were also collected on the three [TAlA][Mn(dca)3] (TAlA = TPrA, TBuA, TPnA) samples (Fig. ), and the calculated partial pair distributions functions were used to aid feature assignment (Figs. ). Short range correlations (up to 10 Å) are ascribed to those between atoms present in a single Mn-dca-Mn linkage (i.e. green bounded portion of Correlations at high-r (> 10 Å) are dominated by those between atoms in adjacent Mn-dca pairs (G ⃡ -I ⃡ ), and as such are more heavily influenced by the increase in A cation size. As expected, changes in the B site metal appeared to have negligible effect on the observed correlations (Fig. ).
