RESUMO
In the structure of the title compound, [Ag(C(12)H(6)N(2)O(2))(2)]BF(4) or [AgL(2)]BF(4) (L = phendione), the Ag and B atoms are located on twofold rotation axes. The dihedral angle between the two phendione ligands is 36.7â (2)°. The coordination about the Ag(I) center is distorted tetra-hedral (τ(4) = 0.546). The crystal structure is consolidated by weak C-Hâ¯O(phendione) and C-Hâ¯F(BF(4) (-)) inter-actions. The BF(4) (-) counter-anion is strongly disordered and was modelled with two sets of idealized F atoms.
RESUMO
In the structure of the title compound, [Ag(C(2)H(3)O(2))(C(12)H(6)N(2)O(2))]·3H(2)O, the Ag(I) atom is coordinated by both 1,10-phenanthroline-5,6-dione N atoms and one O atom from the acetate anion. The three water mol-ecules 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-Hâ¯O inter-actions.
RESUMO
In the structure of the title salt, C(12)H(7)N(2)O(2) (+)·CF(3)SO(3) (-), the cation participates in hydrogen bonding with the dione group of an adjacent cation as well as with the trifluoro-methane-sulfonate anion. In addition, there is an extensive network of C-Hâ¯O inter-actions between the cations and anions. There are two formula units per asymmetric unit. The crystal studied exhibits inversion twinning.
