A spectroscopic peculiarity of two Pt‐related complex defects is interpreted for both of them by assuming one Pt ion in a crystal field, which is tetragonal, though another defect is trigonally coordinated. This coexistence is discussed in the framework of a static Jahn‐Teller effect. Wave functions, compatible with the g‐values, are sketched.
