چکیده
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 dimethylformamide and one water molecule. The coordination polyhedron of each Eu(3+) ion can be described with a distorted monocapped square-anti-prismatic geometry. The mol-ecular structure is stabilized by intra- and inter-molecular hydrogen bonds between the water mol-ecules and benzoate O atoms.

The asymmetric unit of the title complex, [Eu(2)(C(7)H(5)O(2))(6)(C(12)H(8)N(2))(2)]·2C(6)H(5)COOH, contains one-half of the complex mol-ecule, the complete mol-ecule being generated by inversion symmetry, and one benzoic acid solvent mol-ecule. The two Eu(III) ions are linked by four bridging benzoate ions, with an Eu⋯Eu distance of 3.96041 (12) Å. Each Eu(III) ion is coordinated by one phenan...

The title compound, [Pb(2)(C(7)H(5)O(2))(2)(NO(3))(2)(C(12)H(8)N(2))(2)(H(2)O)(2)], crystallizes as a dinuclear centrosymmetric dimer containing two Pb(II) atoms bridged by two benzoate ligands. Each Pb(II) atom is seven-coordinated by a water mol-ecule, a nitrate anion, a 1,10-phenanthroline (phen) ligand and two benzoate anions. The crystal packing is stabilized by O-H⋯O hydrogen bonds and by...

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...
