Abstract

The synthesis, infra-red, Raman and NMR spectra and crystal structure of 2, 4, 4-trimethyl-4, 5-dihydro-3H-benzo [b] [1,4] diazepin-1-ium tetrachlorocadmate, [C 12 H 17 N 2 ] 2 CdCl 4 and benzene-1,2-diaminium decachlorotricadmate(II) [C 6 H 10 N 2 ] 2 Cd 3 Cl 10 are reported.The [C 12 H 17 N 2 ] 2 CdCl 4 compound crystallizes in the triclinic system ( space group) with Z = 2 and the following unit cell dimensions: a = 9.6653(8) Å, b = 9.9081(9) Å, c = 15.3737(2) Å, α = 79.486(1)°, β = 88.610(8)° and γ = 77.550(7)°. The structure was solved by using 4439 independent reflections down to R value of 0.029. In crystal structure, the tetrachlorocadmiate anion is connected to two organic cations through N-H...Cl hydrogen bonds and van der Waals interaction as to build cation-anion-cation cohesion. The [C 6 H 10 N 2 ] 2 Cd 3 Cl 10 crystallizes in the triclinic system ( space group). The unit cell dimensions are a = 6.826 (5)Å, b = 9.861 (7)Å, c = 10.344 (3)Å, α = 103.50 (1)°, β = 96.34 (4)° and γ = 109.45 (3)°, Z = 2. The final R value is 0.053 (Rw = 0.128). Its crystal structure consists of organic cations and polymeric chains of [Cd 3 Cl 10 ] 4anions running along the [011] direction, in the [C 6 H 10 N 2 ] 2 Cd 3 Cl 10 compounds hydrogen bond interactions between the inorganic chains and the organic cations, contribute to the crystal packing.

A new one-dimensional hybrid material lattice: AC conductivity and structural characterization of [C7H12N2][CdCl4]

“…However, each tetrahedron is linked to their neighbors via two edges forming a distortion angle equal to 117°. Theses results are similar to the data known for the tetrachlorocadmate anion [28,29]. The organic molecule exhibits a regular spatial configuration with habitual distances C-C, C-N and angles C-C-C, C-C-N.…”

Dielectric spectroscopy study of the new compound [C12H17N2]2CdCl4

“…Measurements were made over The large empty circles represent nitrogen atoms, the small medium gray circles represent hydrogen atoms, and the black circles represent carbon ones. CdCl 4 2− anions are represented by tetrahedra. Hydrogen bonds are represented by broken lines the temperature range 348-394 K. At each temperature, sufficient time (about 20 min) was allowed for thermal stabilization before taking the measurement.…”

“…The anionic layer is built up tetrahedra of tetrachlorocadmiate CdCl 4 2− arranged in sandwich between two different organic layers. The first one located at z=0 is formed by C 12 N 2 H 17 + (1) cations.…”

“…In this context, we have successfully synthesized a new compound of formula 2,4,4-trimethyl-4,5-dihydro-3H-benzo[b] [1,4] diazepin-1-ium tetrachlorocadmiate ([C 12 H 17 N 2 ] 2 CdCl 4 ) [4]. The analysis of the frequency dispersion of the real and imaginary components of the complex impedance shows that the impedance spectra could be represented by an equivalent circuit represented as parallel combination of resistance and constant phase element.…”

Characterization and Electrical Properties of [C6H9N2]2CuCl4 Compound

“…Indeed, synergy will be critical in achieving targeted physical properties (e.g., electronic, optical and transport properties). Thus, organic-inorganic hybrid materials combine the advantageous properties characteristic of inorganic solids (e.g., high carrier mobilities, thermal stability) with those of organic molecules (e.g., ease of processing, high fluorescence efficiency, and large polarizability) [1][2][3][4][5][6][7][8][9][10][11]. A novel group of crystals, containing heteroaromatic cations like, pyridinium, substituted pyridinium, and imidazolium ones, have been recently synthesized and characterized [11][12][13].…”
