Abstract
Bimetallic oxalate-bridged complexes Q[(MCo)-Co-II(C2O4)(3)] (Q = Me4N+ (Bu 4N+)-N-n, Ph4P+; M-II = Mn, Co, Ni, Cu, Zn) were synthesized. Single crysta ls of [NBu4n][(MnCoIII)-Co-II(C2O4)(3)] were studied by XRD. Unit cell para meters: a = b = 9.242(3) Angstrom, c = 54.524(13) Angstrom; space group R3c . Magnetic measurements indicate the absence of a magnetic phase transition up to the temperature of liquid helium. The XRD data confirm the presence of Co-III ions with a low-spin configuration in the crystal.
