چکیده
The biomolecule chelidonic acid (H2chel, 4-oxo-4H-pyran-2,6-dicarboxylic acid) has been used to build new coordination polymers with the bridging N,N?-ligands 4,4?-bipyridine (4,4-bipy) and 1,2-bis(4-pyridyl)ethane (bpe). Four compounds have obtained as single crystals: 1D cationic [M(4,4-bipy)(OH2)4]2+ chelidonate anions water molecules in second sphere 1?[Zn(4,4-bipy)(H2O)4]chel·3H2O (2) two pseudopolymorphic 1?[Cu(4,4-bipy)(H2O)4]chel·nH2O (n = 3, 4a; n 6, 4b), 2D neutral 2?[Zn(chel)(4,4-bipy)(H2O)]·2H2O (1) 2?[Zn(chel)(bpe)(H2O)]·H2O (3) where anion acts a ligand. effects of hydrogen bonds on crystal packing were analyzed. role hosted within crystals lattices was also studied.

Porous coordination polymers with ubiquitous and biocompatible metals and a neutral bridging ligand
The design of inexpensive and less toxic porous coordination polymers (PCPs) that show selective adsorption or high adsorption capacity is a critical issue in research on applicable porous materials. Although use of Group II magnesium(II) and calcium(II) ions as building blocks could provide cheaper materials and lead to enhanced biocompatibility, examples of magnesium(II) and calcium(II) PCPs ...
