                                摘要:
                                The title complexes, [M(C5O5)(C12H8N2)(2)], with M = Co-II, Ni-II and Cu-II, all lie across twofold rotation axes, around which two 1,10-phenanthroline ligands are arranged in a chiral propeller manner. The Co-II and Ni-II complexes are isostructural, with octahedral coordination geometry, while the local geometry of the Cu-II complex is severely distorted from octahedral.
