The T-c1 = 86 K PT preserves the trigonal symmetry and is associated with the doubling of the c-parameter. At T-c2 = 72 K a doubling of a and b is observed. An intermediate incommensurate phase with q(1) = 1/2c*, q(2) = (1/2 - delta)a* + 1/2c* has been detected in the temperature range of 78-72 K. The lock-in PT at 72 K has a first order character.
