The extended two-dimensional structure is a rectangular grid. The organic ligand acts in an O,N-chelating mode, defining the equatorial plane, while two aqua molecules occupy the axial sites. If, for example, the lining of the nose is chronically inflamed, sinus drainage can cause irritation all the way down the respiratory tract. Stop Being Miserable at Work. LiangAbstract: The crystal structure of the title compound, C15H15NO3, is stabilized by weak O-HO and N-HO hydrogen bonds. The authors of Smart Medicine for Healthier Living say that if a cold gives you a persistent fever, a hacking cough or a rash, you might have a more serious viral infection. SadanandamAbstract: The asymmetric unit of the title compound, C16H19Cl2N3OS, contains two crystallographically independent molecules, which have almost identical conformations. The crystal structure has no classical hydrogen bonds. Both molecules form hydrogen-bonded inversion dimers through their carboxyl groups. After all, who wants to write something that no one reads? Since infancy, my cousin's son has experienced severe asthma attacks and has been hospitalized twice for asthma-related pneumonia. Intermolecular N-HO hydrogen bonds link the cations and anions into ion pairs, which are further linked into zigzag chains by other N-HO hydrogen bonds. BolteAbstract: Molecules of the title compound, C15H9ClO2, are essentially planar.
