| Popis: | The complex cation of the title compound, [Co(C12H8N2)3]2(NO3)4·C12H12N2O6·8H2O, contains a CoII atom with a distorted octahedral coordination environment defined by six N atoms from three bidentate 1,10-phenanthroline ligands. The asymmetric unit of the title compound is completed by one-half of the N,N′-(1,4-phenylenedicarbonyl)diglycine solvent molecule, which is located on a centre of inversion, by two nitrate counter-anions and four solvent water molecules. Two [Co(C12H8N2)3]2+ cations are connected through C—H...O contacts and through lone-pair...π interactions involving the non-coordinating N,N′-(1,4-phenylenedicarbonyl)diglycine and phenanthroline molecules. The different aromatic ring systems are involved in π–π stacking and C—H...π interactions, with centroid-to-centroid distances in the range 3.7094 (8)–3.9973 (9) Å. The crystal structure is stabilized by further anion...π interactions and C—H...O contacts, as well as O—H...O and N—H...O hydrogen bonds between water molecules, the non-coordinating nitrate anions, N,N′-(1,4-phenylenedicarbonyl)diglycine and phenanthroline molecules. These non-covalent interactions give rise to a three-dimensional supramolecular network. |
