Synthesis, structural characterization, Hirshfeld surface analysis and spectroscopic studies of cadmium (II) chloride complex with 4-hydroxy-1-methylpiperidine

The chemical preparation, crystal structure, Hirshfeld surface analysis and spectroscopic characterization of the novel cadmium (II) 4-hydroxy-1-methylpiperidine complex, Cd4Cl10(C6H14NO)(2)center dot 2H(2)O, have been reported. The atomic arrangement can be described as built up by an anionic framework, formed by edge sharing CdCl6 and CdCl5O octahedral linear chains spreading along the a-axis. These chains are interconnected by water molecules via O-H center dot center dot center dot Cl and O-H center dot center dot center dot O hydrogen bonds to form layers parallel to (011) plane. The organic cations are inserted between layers through C-H center dot center dot center dot Cl hydrogen bonds. Investigation of intermolecular interactions and crystal packing via Hirshfeld surface analysis reveals that the H-C center dot center dot center dot Cl and H-C center dot center dot center dot H-C intermolecular interactions are the most abundant contacts of the organic cation in the crystal packing. The statistical analysis of crystal contacts reveals the driving forces in the packing formation. The C-13 and N-15 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. (C) 2015 Elsevier Inc. All rights reserved.
