ABSTRACT

A new cobalt diphosphate (Na0.71Ag0.29)2CoP2O7, is synthesized by solid state reaction method and characterized by single-crystal X-ray diffraction. The title material crystallizes in the triclinic space group P-1 with a = 6.4170(3) , b = 9.4510(2) , c = 10.9350(3) , a = 115.240(2)o, b = 80.190(3)o and g = 106.810(2)0. The structure presents a centro-symmetrical clusters Co4P4O28 consists of two Co2O11 units and two P2O7 pyrophosphate groups. The junction between clusters is assured by two P2O7 groups to form a three-dimensional anionic framework having different interconnecting tunnels running along [100] and [010]. The former contains the Na+ and Ag+ cations. The conductivity measurements of (Na0.71Ag0.29)2CoP2O7 are studied over a temperature interval from 783 to 903 K using the frequency response analyzer with 0.5 V amplitude signal over the range of 13 MHz - 5 Hz.
