“…Common features of all these compounds are the invariable presence of octahedral (CdCl 6 ) units in the anhydrous species. A network of hydrogen bonding, involving organic cations, generally connects the inorganic anions together and stabilizes the whole crystal structure [11][12][13][14]. Therefore, the Cd(II) salt is suitable for the assembly of coordination frameworks.…”

The crystal structure of the new inorganic-organic hybrid compound [4-CH 3 C 6 H 4 CH 2 NH 3 ] 2 [CdCl 4 ] has been determined by single crystal X-ray diffraction. The compound crystallizes in the orthorhombic space group Pnma with lattice parameters a = 10.721(2), b = 33.986(6), c = 5.326(1)Å, β = 97.222(1)• , V = 1940.8(7)Å 3 , and Z = 4. The framework of the title compound is built upon layers parallel to (010) made up from corner-sharing CdCl 6 octahedra. 4-Methylbenzylammonium cations are situated between the layers and connect them via an N-H· · · Cl hydrogen bonding network. The Cd atom is located on an inversion centre, and the coordination environment is described as distorted octahedral. Solid state 13 C CP-MAS NMR spectroscopy is in agreement with the X-ray structure. DFT calculations allow the attribution of the carbon peaks to the independent crystallographic sites. Thermal analysis and infrared spectroscopy were also used to characterize the complex.

“…The powder XRD is homogeneous with single-crystal. Moreover, the infrared spectra confirm the presence of both cationic (C 6 H 10 N 2 ) and the NMR spectroscopy proved to give a rather good insight of the chemical shift relative to 13 C . The studies of optical and luminescence activities reveal that this compound exhibits high stability and has potential applications.…”

“…present very interesting physical properties [8][9][10][11][12]. In this case the Cd (II) ion, being a d 10, was chosen because of its adoption of a variety of coordination numbers and geometries [13][14][15][16] depending on the crystal packing and ligands where the anionic sub-lattice of the crystal may consist of either a simple discrete octahedral, onedimensional chain, or a two-to three-dimensional anionic framework [17,18]. Therefore, the coordination chemistry of Cd (II) ions with such ligands is of interest.…”

In the present work, we synthesized a new hybrid compound, (C 6 H 10 N 2) 2 Cd 3 Cl 10. The crystal structure, vibrational and photoluminescence properties of the compound were studied. The structure can be described by the alternation of two different cationic-anionic layers. It consists of Cd 3 Cl 10 dimers anions and bis Orthophenylenediammonium (C 6 H 10 N 2) cations, which are connected via N-H•••Cl hydrogen bonds forming a chain network. Furthermore, the 3D Hirshfild surfaces and the associated 2D fingerprint plots were investigated for intermolecular interactions in the molecule. The X ray powder is in agreement with the x ray structure. The Infrared Spectrum recorded in the 4000-400 cm-1 frequency region was compared with those found for homologous compounds in the literature. Solid state 13 C NMR spectrum shows three signals, confirming the solid state structure determined by X-ray diffraction. Finally the characteristic exciton peaks in absorption spectra are located at 250 and 494 nm and the photoluminescence measurements showed one peak at around 2.06 eV.

“…It is worth to note that octahedral coordination of Cd(II) is essentially present only in polymeric chlorocadmates(II), although a variety of stoichiometries are possible. The CdCl 6 octahedra can form chains by face, edge, or vertex sharing [11,[18][19][20]. The Cd-Cd distance may be somewhat shorter in the case of 6-coordinated cadmium(II) and face-sharing octahedra forming a chain-cf.…”

One-dimensional chloro-bridged Cd(II) chains separated by dimethyl hexadecyl sulfonium cation layers: synthesis and structure

A low-dimensional material with the composition {(n-C 16 H 33 )(CH 3 ) 2 S} ? +1 [CdCl 3 ] -has been prepared. As expected, the sulfonium cations form an insulating organic layer; the closest Cd-Cd distance between layers is about 19 Å , as compared to 3.9 Å within the same layer. The inorganic layer is formed by a 5-coordinated cadmium(II) moiety CdCl 5 , connected to a one-dimensional chain of slightly distorted, edge-sharing square pyramids. The compound was synthesized from the parent sulfonium chloride and CdCl 2 in ethanol, exploiting the Lewis acidity of Cd(II).
