The synthesis, crystal structure and spectroscopic characterization of the novel 1-(2-hydroxyethyl)piperaziniumtrichlorozincate(II) zwitterionic complex are reported. In the atomic arrangement, the ZnCl 3 N entities, grouped in pairs, are deployed in rows along the a -axis to form layers parallel to the ( a , c ) plane. The organic molecules are inserted between these layers through N-H…Cl, C-H…Cl, O-H…Cl and N-H…O hydrogen bonds to form infinite three-dimensional networks. Intermolecular interactions were investigated by Hirshfeld surfaces. The 13 C and 15 N CP-MAS NMR spectra are in agreement with the X-ray structure. The vibrational absorption bands were identified by infrared spectroscopy. DFT calculations allowed the attribution of the NMR peaks and of the IR bands. [ABSTRACT FROM AUTHOR]

The chemical preparation, crystal structure and spectroscopic characterization of the novel noncentrosymmetric (S)nicotiniumtrichloridozincate monohydrate complex are reported. The atomic arrangement can be described as built up by chains of ZnNCl 3 tetrahedra and water molecules, interconnected via O–H…Cl hydrogen bonds. The organic entities are inserted between these chains through C–H…Cl and N–H…Cl hydrogen bonds. The 3D Hirshfeld surfaces and the associated 2D fingerprint plots were investigated for intermolecular interactions. The 13 C and 15 N CP-MAS NMR spectra are in agreement with the X-ray structure. The vibrational absorption bands were identified by infrared spectroscopy. DFT calculations allowed the attribution of the NMR peaks. [ABSTRACT FROM AUTHOR]
