Magnetic behavior in heterometallic one-dimensional chains or octanuclear complex regularly aligned with metal-metal bonds as -Rh-Rh-Pt-Cu-Pt

Heterometallic one-dimensional chains or octanuclear complex of [{Rh2(O2CCH3)4}{Pt2Cu(piam)4(NH3)4}]n(PF6)2n (1 and 2) and [{Rh2(O2CCH3)4}{Pt2Cu(piam)4(NH3)4}2](CF3CO2)2(ClO4)2·2H2O (3) which are aligned as -Rh-Rh-Pt-Cu-Pt- or Pt-Cu-Pt-Rh-Rh-Pt-Cu-Pt with metal-metal bonds containing unpaired electron on Cu dx2−y2 are characterized by magnetic susceptibilities measurements.192
