Abstract
new 2-D coordination polymer, [Cd(HnicO)(pyc)(H2O)]n (1) (H2nicO = 2-oxynicotinic acid, pycH = pyridine-4-carboxylic acid), and the [Cd3(tartr)3]n salt (2) (tartrH2 = tartaric acid) have been synthesized and structurally characterized. The former is stabilized by H-bonds to give a 3-D architecture. Complex 2, that represents a reinvestigation of Cd tartrate, has been compared with isomorphous [Cd3(tartr)3] structures in terms of the unit cell void and the respective water content, indicating for these compounds the aptitude to crystallize with a small, but different, amount of lattice water. Thermogravimetric and luminescent characterization of 1 were performed.Pubblicazioni consigliate
