We have measured the temperature, magnetic field and angular dependences of the magnetization of a single crystal of a molecular mesoscopic magnet [(C6H15N3)6Fe8O2(OH)12]Br7(H2O)Br·8H2O, Fe8. The molecule Fe8 consists of eight Fe3+ ions with spins of s=5/2. The experimental results of the magnetizations at low temperatures show large anisotropy that is dependent on the orientation of the external magnetic field with respect to the crystal axis. These results are well explained by the Hamiltonian for an isolated molecule with total spin S=10 and anisotropies of D=-0.276 K and E=-0.035 K. The easy axis is determined to be oriented with an azimuthal angle of 16° from the a-axis in the ab-plane and an inclinational angle of 0.7° from the ab-plane.
