The synthesis, crystal structure and spectroscopic characterization of the novel 1-(2-hydroxyethyl)piperaziniumtrichlorozincate(II) zwitterionic complex are reported. In the atomic arrangement, the ZnCl3N 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 13C and 15N 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. © 2016 Elsevier B.V. All rights reserved.

1-Ethylpiperazinediium pentachloroantimonate (III) monohydrate, C6H16N2SbCl5·H2O, has been synthesized by the reaction of antimony trioxide (Sb2O3) and 1-ethylpiperazine in an aqueous solution of hydrochloric acid. The structure crystallizes in orthorhombic system, in the non-centrosymmetric space group Pca21 and consists of isolated [C6H16N2]2+ cations, square pyramidal [SbCl5]2− anions and lattice water molecules. [Formula presented] hydrogen bonds link the [SbCl5]2− anions and water molecules to form double chains stretching along the [101] direction. The chains in turn are linked to the organic cations via [Formula presented], [Formula presented], [Formula presented] and [Formula presented] hydrogen bonds to form a three-dimensional network. This structure presents an example of a general square pyramidal complex ion containing a stereo-chemically active lone pair of electrons. Solid state 13C and 15N CP-MAS NMR spectra are in agreement with the X-ray structure, and vibrational absorption bands were identified by infrared spectroscopy. DFT calculations allowed the attribution of the NMR peaks and IR absorption bands. The interactions variability of the two independent cations and ten chloride atoms is analyzed via Hirshfeld surface analysis. © 2016 Elsevier Masson SAS

The asymmetric unit of the title compound, (C 7H 7N 2S) 2[ZnCl 4], contains a network of 2-amino-benzothia-zolium cations and tetra-hedral [ZnCl 4] 2- anions. The crystal packing is influenced by cation-to-anion N - H⋯Cl and C - H⋯Cl hydrogen bonds. The [ZnCl 4] 2- anions have a distorded tetra-hedral geometry. Inter-molecular π-π stacking inter-actions are present between neighboring benzene rings, thia-zole and benzene rings and neighboring thia-zole rings [centroid-centroid distances = 3.711 (2), 3.554 (1), 3.536 (2) and 3.572 (1) Å].
