Electrical properties of new organo-inorganic layered perovskites

This paper deals with the synthesis of new halide complexes with the general formula (choline)(2)[Cu-y M1-yX4] (where choline(+)-is quaternary ammonium ion of 2-amino-1-ethanol, [(CH3)(3)N+-(CH2)(2)-OH] and M = Sn; y = 0; 0.25; 0.50; X = Cl or I; M = Pb; y = 0; 0.25; 0.50; 0.75; X = I), (choline)(2)[FeyPb1-yX4] (y = 0; 0.25; 0.50; X = Cl or y = 0.50; X = I) and (choline)(2)[Cu0,50Fe0,25Pb0,25I4], having layered perovskite-like structure. The synthesized series of halide complexes have been characterized by elemental, spectral and thermal analysis, X-ray diffraction and electric conductivity measurements.
