s7Fe Mossbauer and magnetometric studies of molecular ferrimagnet N(n-CBHii)4[FenFein(C204)3] are indicative of a 2D magnetic character with strong uniaxial anisotropy in the crystal's basal plane. It is established that the change in the sign of the net magnetization of this compound is related to a compensation between Fem and Fe11 sublattice magnetizations at TCOmp = 31.2 K. The form and parameters of the magnetic Hamiltonian describing the temperature dependence of the Fe111 sublattice and the net magnetizations has been determined.
