Crystal Growth and Characterization of a New Tetrameric Complex of Ba(II) with Pamoic Acid
A new tetrameric complex of Ba(II), [Ba4(PA)4(H2O)20]·4H2O (PA = pamoate) has been prepared by gel diffusion technique at ambient condition. The grown crystals were characterized by elemental analysis, single crystal X-ray diffraction studies, thermogravimetry, FT-IR and UV–visible spectral studies. The single crystal X-ray diffraction studies show that the crystal structure consists of two different types of nine coordinated Ba centers (Ba1 and Ba2). In addition to the carboxylate groups of pamoate, two coordinated water also interconnect the Ba(II) centers. The carboxylate groups of pamoate exhibit monodentate, bismonodentate and bidentate, coordination modes with Ba(II) ions. Hydrogen bonding further stabilizes the crystal structure. Photoluminescence studies were also carried out.
Graphical Abstract
A new tetrameric complex of Ba(II) with pamoic acid (H2PA) of formula [Ba4(PA)4(H2O)20]·4H2O (BaPA) has been prepared by gel diffusion technique at ambient condition and is characterized by various analytical techniques.
期刊介绍：
Journal of Chemical Crystallography is an international and interdisciplinary publication dedicated to the rapid dissemination of research results in the general areas of crystallography and spectroscopy. Timely research reports detail topics in crystal chemistry and physics and their relation to problems of molecular structure; structural studies of solids, liquids, gases, and solutions involving spectroscopic, spectrometric, X-ray, and electron and neutron diffraction; and theoretical studies.
