We describe the synthesis and the structural characterization of new H2L(CF3CO2)2 (1)and H2L(Ph2PO4)2 (2) compounds containing the diprotonated form (H2L2+) of the tetrazine-basedmolecule 3,6-di(pyridin-4-yl)-1,2,4,5-tetrazine. X-ray diffraction (XRD) analysis of single crystalsof these compounds showed that H2L2+ displays similar binding properties toward both anionswhen salt bridge interactions are taken into account. Nevertheless, the different shapes, sizes andfunctionalities of trifluoroacetate and diphenyl phosphate anions define quite different organizationpatterns leading to the peculiar crystal lattices of 1 and 2. These three-dimensional (3D) architecturesare self-assembled by a variety of non-covalent forces, among which prominent roles are played byfluorine– (in 1) and anion– (in 2) interactions.

X-ray diffraction (XRD) analysis of single crystalsof these compounds showed that H2L2+ displays similar binding properties toward both anionswhen salt bridge interactions are taken into account. Nevertheless, the different shapes, sizes andfunctionalities of trifluoroacetate and diphenyl phosphate anions define quite different organizationpatterns leading to the peculiar crystal lattices of 1 and 2. These three-dimensional (3D) architecturesare self-assembled by a variety of non-covalent forces, among which prominent roles are played byfluorine– (in 1) and anion– (in 2) interactions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
