Bis(1,10-phenanthroline-5,6-dione-κ2 N,N′)silver(I) tetra­fluoridoborate

In the structure of the title compound, [Ag(C12H6N2O2)2]BF4 or [AgL 2]BF4 (L = phendione), the Ag and B atoms are located on twofold rotation axes. The dihedral angle between the two phendione ligands is 36.7 (2)°. The coordination about the AgI center is distorted tetra­hedral (τ4 = 0.546). The crystal structure is consolidated by weak C—H⋯O(phendione) and C—H⋯F(BF4 −) inter­actions. The BF4 − counter-anion is strongly disordered and was modelled with two sets of idealized F atoms

5,6-Di­oxo-1,10-phenanthrolin-1-ium trifluoro­methane­sulfonate

In the structure of the title salt, C12H7N2O2 +·CF3SO3 −, the cation participates in hydrogen bonding with the dione group of an adjacent cation as well as with the trifluoro­methane­sulfonate anion. In addition, there is an extensive network of C—H⋯O inter­actions between the cations and anions. There are two formula units per asymmetric unit. The crystal studied exhibits inversion twinning

Acetato(1,10-phenanthroline-5,6-dione)silver(I) trihydrate

In the structure of the title compound, [Ag(C2H3O2)(C12H6N2O2)]·3H2O, the AgI atom is coordinated by both 1,10-phenanthroline-5,6-dione N atoms and one O atom from the acetate anion. The three water mol­ecules are involved in extensive hydrogen bonding to each other and to the acetate O and 1,10-phenanthroline-5,6-dione O atoms. In addition, there are weak C—H⋯O inter­actions
