The influence of benzoate anions on the corrosion inhibition effect of benzotriazole (BTA) for mild steel in sulfuric acid has been investigated. The investigation was carried out by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization techniques. The addition of benzoate ions greatly enhances the inhibition efficiency of BTA in a synergistic manner. This effect has bee...

The title compound, [Eu2(C7H5O2)6(C15H11N3)2(H2O)2]·2C7H6O2, is a co-crystalline compound containing a dinuclear Eu(III) coordination complex with inversion symmetry co-crystallized with benzoic acid in a 1:2 ratio. The Eu(3+) ions within the dimer are nine-coordinate, containing one tridentate terpyridine, one water, and four benzoate ions, two of which bridge the Eu(3+) ions. Of the four benz...

In title compound, [Ca(C(7)H(5)O(2))(2)(C(7)H(6)O(2))(H(2)O)](n), the eightfold-coordinated Ca(II) ion is bonded to four carboxyl-ate O atoms from two benzoate ions, an O atom from benzoic acid and a water O atom. One of the carboxyl-ate groups bridges adjacent Ca(2+) ions, forming a polymeric ribbon structure parallel to [010]. In the crystal, the benzoate anions and water mol-ecule inter-act ...

The title dimeric complex, [Eu(2)(C(7)H(5)O(2))(6)(C(3)H(7)NO)(2)(H(2)O)(2)], is centrosymmetric, implying that pairs of equivalent Eu(3+) ions and ligands lie trans to each other and that the two Eu(3+) ions have exactly the same coordination environment. Each Eu(3+) ion is nine-coordinated by two bidentate benzoate ligands, two bridging tridentate chelating benzoate ligands, and one dimethylf...

The dinuclear title compound, [Cd(2)(C(7)H(5)O(3))(4)(C(12)H(8)N(2))(2)], is located on a crystallographic rotation twofold axis. The two Cd(II) ions are connected by two tridentate bridging 2-hydroxy-benzoate anions. Each Cd(II) ion is seven-coordinated by five O atoms from three 2-hydroxy-benzoate ligands and two N atoms from 1,10-phenanthroline. The 2-hydroxy-benzoate mol-ecules adopt two ki...

In the centrosymmetric dinuclear title compound, [Pb(2)(C(7)H(5)O(2))(4)(C(12)H(8)N(2))(2)], two Pb(2+) ions are connected by two tridentate bridging benzoate anions. The Pb(2+) ion is seven-coordinated by five O atoms from three benzoate anions and two N atoms from the 1,10-phenanthroline ligands. The benzoate anions adopt two different coordination modes, one bidentate-chelating and one tride...

In the title compound, [Zn(C(8)H(5)O(3))(2)(C(6)H(6)N(2)O)](n), the Zn(II) ion is tetrahedrally coordinated by two formyl-benzoate (FB) and one isonicotinamide (INA) ligands while symmetry-related FB ligands bridge adjacent Zn(II) ions, forming polymeric chains along the b axis. The carboxyl-ate groups in the two FB ions are twisted away from the attached benzene ring by 9.07 (2) and 26.2 (2)°....
