The structure of a linear chain compound (CH.).NHCdCI. was investigatedat 355 K using a four-circle diffractometer. The structure belongs to the ortho-rhombic svstem, srace gtOUp Pbnm. Unit cell dimensions are a=17.]23 A,b= 15.256 A, c= 6.731 A and Z= 8. The structure was refined by a block-diagonalleast squares method. The obtained result in general agrees with the modelreported previously. The disorder state of the trimethy7 ammonium ions withunequal occupation propabilities is discussed. The mechanism of the phasetransition from the room temperature (I x A/3) phase to the high temperature(2 x (3) phase is also discussed.
