Bis(μ-2-hydroxy-benozato)-κO,O':O';κO:O,O'-bis-[(2-hydroxy-benozato-κO,O')(1,10-phenanthroline-κN,N')cadmium(II)].

ABSTRACT: 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 kinds of coordination mode, bidentate chelating and tridentate bridging-chelating. Intra-molecular hydrogen bonds between hydr-oxy and carboxyl-ate groups from 2-hydroxy-benzoate groups and π-π stacking interactions between parallel 1,10-phenanthroline ligands [centroid-centroid distances = 3.707 (3) and 3.842 (3) Å] are observed. Furthermore, adjacent benzene rings from 2-hydroxy-benzoate ligands are involved in π-π inter-actions with inter-planar distances of 3.642 (3) Å, thereby forming a chain along the a axis direction.
