摘要：

The reaction of LCr(III) units with Fe(II)(salox) units, (L = 1,4,7-trimethyl-1,4,7-triazacyclononane and H-2salox = salicylaldehyde oxime), produces in situ in methanol and in the presence of air, a small amount of triethylamine, NaClO4 and the dark-brown complex [L2Cr2(OMe)2O2(salox)2Fe2](ClO4)2.3H2O, which has been characterized by X-ray crystallography and magnetic susceptibility measurements and found to have a non-diamagnetic (S(T) not-equal 0) ground state due to spin frustration.
