چکیده
The title compound, (C(10)H(10)N(2))[Sb(2)(C(7)H(2)NO(5))(2)(OH)(2)(H(2)O)(2)]·2H(2)O, consists of a binuclear anion, a diprotonated 4,4'-bipyridinium cation and two uncoordinated water mol-ecules. Each Sb(III) atom is six-coordinated by one chelating 4-oxidopyridine-2,6-dicarboxyl-ate ligand, one water mol-ecule, one OH group and one bridging O atom from a neighboring carboxyl-ate group in a distorted penta-gonal-pyramidal geometry, with the OH group at the apical position. The two pyridine rings in the bipyridinium cation are twisted with respect to each other, making a dihedral angle of 22.7 (1)°. The cations are connected to the anions by N-H⋯O hydrogen bonds, forming a chain. The coordinated water mol-ecules form hydrogen bonds with the oxido O atoms of the anion, building a two-dimensional sheet, which is further connected into a three-dimensional structure by O-H⋯O and C-H⋯O hydrogen bonds and C=O⋯π inter-actions [O⋯centroid distances = 3.1785 (17), 3.4737 (19) and 3.5685 (19) Å].

In the title compound, [Ag(2)(C(14)H(14)N(4))(2)](C(14)H(8)N(2)O(4))·2H(2)O, each of the two unique Ag(+) ions is two-coordinated by two N atoms from two different 1,4-bis-[(imidazol-1-yl)meth-yl]benzene ligands in an almost linear fashion [N-Ag-N = 170.34 (10) and 160.25 (10)°]. The 4,4'-diazenediyldibenzoate anions do not coordinate to Ag. O-H⋯O hydrogen bonds stabilize the crystal structure.
