title: Selective anion encapsulation in solid-state Ln(III)[15-metallacrown-5]3+ compartments through secondary sphere interactions.
abstract: Secondary sphere interactions from proximal phenyl side chains control the anion selectivity of dimeric Ln(III)[15-MC(Cu(II),α-aminoHA)-5](3+) metallocavitands. CH-O interactions, which are only possible with certain side chains, are sufficient for overcoming an intrinsic energy barrier to binding saturated dicarboxylates in hydrophobic compartments.
