ABSTRACT
A new proton-transfer organic salt, quinolinium hydrogensquarate (C13H9NO4), has been synthesized and fully characterized by single crystal x-ray diffraction. The salt crystallizes in the monoclinic space group P21/n with the parameters: a = 3.8290(12) Å, b = 20.960(6) Å, c = 13.802(4) Å, β = 95.452(5)°, V = 1102.7(6) Å3, Z = 4 formula units. The structure consists of uncommon supramolecular neutral dimers which pile up parallel to [100] forming infinite sheets. These centrosymmetric dimers are held together by lateral hydrogen-bonds whereby two neighboring coplanar hydrogensquarate anions act as a bridge between two terminal quinolinium cations and C-H…O bridgings interlink next neighboring sheets. The bulk structure of this salt is consolidated by weak π-π interactions within the sheets which are neatly ordered side-by-side relative to one another.
