Ahmed, M. A., and M. A. Mousa, "Temperature effect on magnetic and electrical properties of the compound Fe(DMSO)2Cl2", Journal of Materials Science Letters, vol. 8, issue 1, pp. 104 - 106, 1989. AbstractWebsite

X-ray structural analysis on (FeCl(DMSO)5)(Fe2-Cl6O) complex have shown that the position of the dimethylsulphoxide molecule (DMSO) became distorted between two positions with increasing temperature. The disorder in this compound is due to the tendency of the angle of the oxobridge of the anion (Cl3Fe-O-FeCl3) to straighten out, the effect being transmitted to the cation via the short Cl-S contact. This letter reports a study of the effect of temperature on the magnetic susceptibility, dielectric constant and electrical conductivity of the neutral complex ((DMSO)2FeCl2). This complex was found to have a distorted square planar complex at room temperature, with two chloride ions and two oxygens of sulphoxide groups lying around the Fe2+ ions. Such studies may yield information about the effect of temperature on the structure and the donor sites of DMSO in this type of complex.

Summan, A. M., M. A. Mousa, M. A. Ahmed, and A. M. Badawi, "Thermal and electrical studies on some two-dimensional chelated compounds", Thermochimica Acta, vol. 140, issue C, pp. 229 - 236, 1989. AbstractWebsite

The temperature dependence of the electrical conductivity σ of some two-dimensional chelated compounds ((ODA)FeCl4, (ODA)1 2(Cyst)FeCl4, (ODA)CuCl4 and (ODA)1 2 (GA)CuCl4, where ODA = octanediammonium ion. Cyst = cystinium ion, GA = glucosam- monium ion) was investigated. Differential scanning calorimetry measurements of these compounds show the presence of more than one structural phase transition for each compound. These phase transitions are also observed in the conductivity results. Seebeck voltage measurements show that electrons are the majority charge carriers in all the crystal phases of the complexes. © 1989.

Mousa, M. A., M. A. Ahmed, A. M. Summan, and A. M. Badawy, "γ-Irradiation effects on the electrical conductivity of some two-dimensional complexes: RMnCl4, RCoCl4 and RMn0.5Co0.5Cl4 (R = H3N-(CH2)8-NH3)", Thermochimica Acta, vol. 146, issue C, pp. 87 - 93, 1989. AbstractWebsite

DTA, d.c. conductivity and thermoelectric power of the compounds RMnCl4, RCoCl4 and RMn0.5Co0.5Cl4 (R = H3N-(CH2)8-NH3) were measured over a temperature range of 300-500 K. Both the DTA and the d.c.-conductivity results show the presence of many phase transitions in each of the complexes investigated. The conductivity results are explained on the basis of an electron-hopping mechanism. The effect of γ-irradiation on the conductivity data and the type of crystal phase are investigated and discussed. © 1989.
