The reaction of oxalic ac id, metal(lI) salt and tetra(n-butyl) ammonium bromide or dimethyl dioctadecyl ammonium bromide in a molar ratio of 1.5: I: I in water or ethanol-water at room temperature afforded polymetallic assemb lies with the formulae (NBu.MM 2 (OXU}. [M = Mn 2 '(1), Fe 2 +(2), Co 2 +(3)] and {(DMDOAMMiOXU} . [M = Mn!+(4), Fe 2 +(S), Co h (6) ] . The magnetic susceptilbility dafa of 5 and 6 in the range 20 K < T < 300 K obey the Curie-Weiss law and on lowering th e temperature
