|Description||Two new complexes of Eu(III) and Tb(III) with the new ligand N,N′,N″-(1,3,5-triazine-2,4,6-triyl) tribenza mide (TBZM) and benzoate (BA) have been isolated and crystallographically characterized [Tb(BA)2(TBZM)(H2O)]2(CF3SO3)2·4CH3CN·2H2O, 1, crystallizes in the triclinic P-1 lattice with unit cell parameters a = 11.3018(8), b = 14.3390(5), c = 16.4758(5) Å, α = 114.036(2)°, β = 106.112(2)°, γ = 90.916(2)° and V = 233.40(14) Å3. The related complex [Eu(BA)2(TBZM)(H2O)]2(NO3)2·12.4H2O, 2, crystallizes in the triclinic P-1 lattice with unit cell parameters a = 12.2537(2), b = 13.0210(3), c = 15.7362(3) Å, α = 71.083(1)°, β = 80.628(1)°, γ = 80.910(1)° and V = 2328.55(8) Å3. Both complexes display the metal center with coordination number 8 in a square-antiprismatic geometry. Extensive hydrogen-bonding interactions, which extend the homobinuclear molecules into three-dimensional architectures, are present in both compounds. In the first case, triflate counter-ions, benzoate ligands and solvent water and acetonitrile molecules and, in the second case, the TBZM ligands, nitrate counter-ions and solvent water molecules are involved in these interactions. Finally, in the Eu(III) complex, the three-dimensional structure is further supported by π-π interactions involving benzamide phenyl rings and triazine rings.|
