Although the chemical properties of organic tin compounds have been investigated by numerous workers, little is known about their electrical properties or applications.
The authors have investigated the insulating resistance, dielectric properties and magnetic susceptibilities of tetraethyltin (T. E. T.), tetra-n-propyltin (T. nP. T.), and tetra-n-butyltin (T. nB. T.) which are organic tin compounds with symmetrical molecular structure. It has been found that
(1) the insulating resistance R of T. nP. T. is 8. 5×10
9 (Ω.cm) at room temperature and the activation energy obtained from the slope of curve log
10 R-1/
T is 0.32 (eV). (2)the values of the dielectric constants of T. E. T. and T. nP. T. are ε
E=2.241 and ε
P=2.267, respectively, which are smaller than the dielectric constant of dry benzene ε
B=2.291 at 20°C. (3) the mesured values of molecular susceptibility χ
M (10
-6cm
-3/mol) of T. E. T., T. nP. T. and T. nB. T. are 165, 216, and 262, respectively, and these values are in satisfactory agreement with the theoretical values calculated by the Augus method.
