An X-ray study of successive phase transitions on K.SeBrz has been pc:rformedand the results were interpreted on tube stand point of the condensation. of therotary modes of SeBr5 octahedra. The rotary modes belong to the ir?'educibIerepresentations: X" ([0014 zone boundary mode) and T" (zone centc:r mode)of space group Fm3m. It has been shown that the symmetry of the crysl:al trans-forms sequentially with decreasing temperature as Fm3m-+P4/mnc-+C2/n=P2./n. This sequential transition scherne is explained by postulating the s'uccessivecondensations of the rotary modes at the transition points in the sequence ofX4 f = f 4 f = 7 4 f .
