چکیده
|
The title compound crystallizes in monoclinic system p21/c. the parameters of the unitcell are: a=6.856(5)å; b=13.070(5)å; c=11.370(2)å; β=98.63(3)°; v=1007.2(5)å^3 and z=4. theanionic framework of the compound is built up from infinite layers linked together by mn-as-obridges and by edge-sharing mno6 octahedra to form a three dimensional framework having two kinds of tunnels. the first one, containing k^+ cations, is parallel to the a axis and the second one containing na^+ cations is parallel to [001] direction. complementary infrared (ir) and complex impedance (ci) spectroscopies studies were carried out.
