S where 3-EtO-SalAPA is the monoanionic Schiff base derived from 3-ethoxysalicylaldehyde and N-(3-aminopropylaziridine and S is C6H5F, C6H5Cl, C6H5Br, C6H5I or o-C6H4Cl2. Their gradual nature of spin-state interconversion is evidenced by the variable-temp. magnetic susceptibility and EPR data. Only a single quadrupole-split doublet is seen in the Moessbauer spectra for all solvates in the temperature range of
