Diaqua-(2,6-dihy-droxy-benzoato-κO,O)bis-(2,6-dihy-droxy-benzoato-κO)bis-(1,10-phenanthroline-κN,N')lanthanum(III)-1,10-phenanthroline (1/1).

ABSTRACT: In the title compound, [La(C(7)H(5)O(4))(3)(C(12)H(8)N(2))(3)(H(2)O)(2)]·C(12)H(8)N(2), the La(III) atom is coordinated by four N atoms from two chelating 1,10-phenanthroline (phen) ligands, four O atoms from three 2,6-dihy-droxy-benzoate (DHB) anions (one monodentate, the other bidentate) and two water O atoms, completing a distorted LaN(4)O(6) bicapped square-anti-prismatic geometry. Within the mononuclear complex mol-ecule, intra-molecular π-π stacking inter-actions are observed, the first between a coordinated phen mol-ecule and a DHB ligand [centroid-centroid distance = 3.7291 (16) Å], and the second between a coordinated phen mol-ecule and an uncoordinated phen ligand [centroid-centroid distance = 3.933 (2) Å]. Inter-molecular π-π stacking is observed between adjacent complexes [inte
