Abstract

A new strategy for the preparation of molecular magnets by the reduction of phthalocyanines with strong metallocene donors has been suggested. Compound (Cp*₂Cr⁺)·(Fe^IPc⁻)·(C₆H₄Cl₂)₄ (1) contains uniform stacks of alternating closely packed Cp*₂Cr⁺ and Fe^IPc⁻ ions. 1 is a soft ferrimagnet showing hysteresis with a small coercive field and a bifurcation temperature of about 5 K.
