| Abstract: | Bimetallic oxalate-bridged complexes QMIICo(C2O4)3] (Q=Me4N+, Bun 4P+; MII=Mn, Co, Ni, Cu, Zn) were synthesized. Single crystals of NBun 4]MnIICoIII(C2O4)3] were studied by XRD. Unit cell parametersa=b=9.242(3) Å,c=54.524(13) Å; space groupR3c. Magnetic measurements indicate the absence of a magnetic phase transition up to the temperature of liquid helium. The XRD data confirm the presence of CoIII ions with a low-spin configuration in the crystal. |
