A certain class of low-dimensional molecular magneticic systems is reviewed. Both a numerical quantum transfer-matrix approach and an exact diagonalization technique are presented. The approach is applied to some supramolecular clusters contining Mn and Ni ions and to a number of macroscopic magnetic spin S = 1 chains, with uniform and alternating couplings and single-ion anisotropy. The results of our simulations are compared with the available experimental results, showing an overall quantitative agreement
