Four sodium tetrafluoroborate directed supramolecular networks having 3- and 3,8-disubstituted 1,10-phenanthroline ligands

Four novel sodium tetrafluoroborate directed supramolecular networks 1-4 having 3- and 3,8-disubstituted 1,10-phenanthroline (phen) ligands are structurally characterized, where the rare monodentate coordination mode for the phen-based ligand, the presence of uncommon three and four-coordinate sodium(I) coordination centers and sodium(I)-thiophene coordination bonds are found.
