We treat the organic system mMPYNN-BF_4 as a network of hexagons. Each hexagon contains six S = 1/2 spins coupled alternately with ferro- and antiferromagnetic interactions. The antiferromagnetic coupling between hexagons is treated as a perturbation term. We obtain the ferro- and antiferromagnetic coupling constants in the hexagon and the antiferromagnetic coupling constant between hexagons. The susceptibility calculated by the second-order perturbation method for mMPYNN-BF_4 agrees well with the experimental results. The ground state energy is also calculated.
