An interesting pseudo-honeycomb supramolecular arrangement obtained from the interaction between 4-aminosalicylic acid, trans-1,2-bis(4-pyridyl)ethylene and transition metal ions†

摘要: In this work, three new compounds containing coordination polymers named [Co(bpe)(H2O)4]AS2·4H2O (1), [Ni(bpe)(H2O)4]AS2·4H2O (2) and [Zn(bpe)(H2O)4]AS2·4H2O (3) (where AS is aminosalicylate anion bpe trans-1,2-bis(4-pyridyl)ethylene) were synthesized characterized by X-ray diffraction vibrational spectroscopy (infrared Raman). All complexes are isomorphous, crystallizing in a monoclinic system with space groupP21/c. The crystalline arrangement shows the presence of cavity called pseudo-honeycomb imperfect, parallel to bc-plane formed through hydrogen bonding between anions water molecules crystallization. spectra very similar, agreement crystal data. Raman show bands for at 1642 1614 cm−1, assigned ν(CC) ν(CC)/ν(CN), respectively. This study can be considered as first work literature where associated just filling cavities structures.
