Polarized single crystal absorption spectra, in the spectral range 40 000-5 000 cm-1, were obtained on Co 2+ in trigonally distorted octahedral oxygen fields of buetschliite-type K2Co(SeO3) 2 (I), KzCoz(SeO3) a (II) and zemannite-type K2Co2(SeOa)3.2H20 (III). Site symmetries of Co 2+ are 3m (Dad) in
