چکیده
In the title compound, [Nd(2)(C(6)H(3)BrNO(2))(6)(H(2)O)(4)]·2H(2)O, the Nd(III) ion is coordinated by nine O atoms from one chelating 5-bromo-nicotinate ligand, four bridging 5-bromo-nicotinate ligands and two water mol-ecules, exhibiting a distorted three-capped triangular-prismatic geometry. Two Nd(III) ions are bridged by four carboxyl-ate groups in bi- and tridentate modes, forming a centrosymmetric dinuclear unit, with an Nd⋯Nd distance of 4.0021 (5) Å, and intra-molecular π-π inter-actions between the pyridine rings [centroid-centroid distance = 3.960 (2) Å]. Inter-molecular π-π inter-actions [centroid-centroid distances = 3.820 (2) and 3.804 (2) Å] and O-H⋯N and O-H⋯O hydrogen bonds connect the dinuclear mol-ecules into a three-dimensional supra-molecular network.
