MAGNETIC-PROPERTIES OF E(CN)(6)](2)CENTER-DOT-XH(2)O-CENTER-DOT(M=CO(II), NI(II), CU(II), ZN(II))

Compounds of the type M(3)[Fe(CN)(6)](2) . XH(2)O (M = Co(II), Ni(II), Cu(II), and Zn(II)) were prepared and magnetic properties of their po wders were investigated by means of EPR spectra, Mossbauer effect and magnetic susceptibility measurements. The temperature dependence of th e magnetization for the complexes Co3[Fe(CN)6]2 . 10H(2)O, Ni-3[Fe(CN) (6)](2) . 10H(2)O and Cu-3[Fe(CN)6]2 . 4H(2)O revealed that below the critical temperatures 15, 22 and 20 K respectively, these complexes ha ve zero-field magnetization. The magnetic hysteresis at 10 K for Co(II ), Ni(II) and Cu(II) complexes was observed. Mossbauer spectra at 4.2 K for the compounds are discussed.
