SYNTHESIS OF MOLECULAR FERROMAGNETICS [R(3)R'X]MCR(C2O4)(3) (X=N, R=BU(N), R'=PR-N, ET, ME - X=P, R=PH, R'=BU(N), M=MN, FE, CO, NI, CU)

The synthesis, IR spectra, and the temperatures of the transition into a ferromagnetic state (T-c) of layered ferromagnetics [R(3)R'X]MCr(C2 O4)(3) (M = Mn, Fe, Co, Cu, and Ni) with the [Ph(3)BuP](+), (Bu(3)R'N] (+) (R' = Pr, Et, and Me) cations capable of subsequently changing the distances between metallooxalate layers have been considered. The tem perature T-c has been found to be independent of the size of the organ ic cation. It is believed that the determining factors in the transiti on to a ferromagnetic state are exchange interactions inside the metal looxalate layer.
