Abstract
A new organiceinorganic hybrid material, bis (N, N-dimethylbenzylammonium) tetrachlorocobaltate (II), (C9H14N)(2)CoCl4 was synthesized and analyzed by X-ray diffraction. Magnetization was used to investigate the magnetic properties. The structure was determined at room temperature in the triclinic space group P-1 with the following parameters: a = 10.491 (5) angstrom, b = 14.207 (2) angstrom, c = 16.187 (3) angstrom, alpha = 87.76 (3) angstrom, beta = 88.436 (8) angstrom, gamma = 89.897 (10) angstrom and Z = 2. The structure can be described by the alternation of organicinorganic layers parallel to (110) plan. The different components are connected by the N-H center dot center dot center dot Cl hydrogen bonds between the cation and the anionic group [CoCl4](2-). Raman and infrared spectra were used to gain more information of the title compound. An assignment of the observed vibration modes is reported. This compound exhibits an antiferromagnetic (AFM) to paramagnetic (PM) phase transition at a temperature (T-N) lower than 2 K. The values of paramagnetic CurieeWeiss temperature theta(CW), the nearest neighbor interaction Jnn, the classical nearest neighbor J (cl) and the dipolar D-nn interactions' emphasize the existence of an antiferromagnetic interaction between the neighboring cobalt ions.
