ABSTRACT
The title compound, [Cd(C(7)H(5)O(3))(2)(C(10)H(8)N(2))(2)]·CH(3)OH, contains one monomeric seven-coordinate cadmium complex and one methanol solvate mol-ecule. The Cd(II) atom is coordinated to two 2,2'-bipyridyl ligands via the N atoms and to two salicylate anions (Hsal(-)) via the carboxyl-ate O atoms, which act as monodentate ligand for the one and bidentate ligand for the second. The Cd(II) atom exhibits a {6 + 1} environment, approximately described as a distorted capped octa-hedron with the apical positions occupied by one of the two N atoms belonging to one bipyridyl ligand and one of the two carboxyl-ate O atoms from the monodentate Hsal(-) ligand. Two intra-molecular six-membered hydrogen-bonded rings are present, generated from inter-actions between the carboxyl-ate and hydr-oxy groups of the salicylate ligands. There is one inter-molecular hydrogen-bonding inter-action involving the methanol solvent mol-ecule and the carboxyl-ate group from the monodentate Hsal(-) ligand. The crystal packing is governed by π-π stacking inter-actions [centroid-centroid distance = 3.783â
