Abstract
Local structures around Pb(II) and Sn(II) in CH(3)NH(3)PbX(3) (X=Cl, B r, I) and CH(3)NH(3)SnX(3) (X=Br, I) were studied by Pb L(III)-edge an d Sn K-edge EXAFS in the temperature range of 10 to 293 K. The M-X dis tances (M=Pb, Sn; X=Cl, Br, I), the coordination numbers, and the Deby e-Waller factors were determined in three, four, three, five, and two solid phases of CH3NH3PbCl3, CH3NH3PbBr3, CH3NH3PbI3, CH3NH3SnBr3, and CH3NH3SnI3, respectively. Five kinds of deformed octahedra consisting of halogens were observed.
