Magnetic anisotropies of several mangane secryst,als have been naeasured accu-rately between 77 K and 300 K by using a high sensitive torque-naeter. ,As ispredicted by the high temperature expansion th<cory, the observed naagneticanisotropies vary as the inverse square of the tempe.rature. The crystal field split-ting parameters D and E have been obtained for<>ach pure magnetically densesanuple. In compounds having the octahedron witla two water molecules alongthe axial direction, the splitting parameters D have been found to be about -0.1cm-', which value is two tiznes or one order of mag;nitude larger than the typicalvalue of Mn" surrounded by a distorted octaheclron composed of six si.milarligands. Especially, the value 17)l =0.368 cm ' fo'ar [(CH.).NlI]MnBr.2I-[.0 isthe largest one reported to date.
