Engineering organic/inorganic diols that reversibly capture and release volatile guests
Alessia Bacchi, Elsa Bosetti and Mauro Carcelli
The structural and clathrating behaviour of some trans-M(LOH)2Xn(M = Ag+, Pd2+; X = anion) complexes is studied. The role of anions and included solvent molecules in inducing supramolecular isomerism is discussed. The toolbox of supramolecular interactions which can be used for the assembly of these systems involves mainly OH
OH and OHX hydrogen bonds, and can be mediated by the guest molecules (G)via OHG interactions. The diverse supramolecular configurations of some anion-mediated Ag(LOH)2X (X = BF4, PF6) networks are analysed. In the solvent-mediated crystal networks of Pd(LOH)2X2·nG (X = Cl, I, CH3, CH3COO; G = acetone, tetrahydrofuran, dimethylsulfoxide, dimethylformamide, 1,4-dioxane), the substructures built by the solvent domains are discussed in relation to the solvation/desolvation processes.
