description

Abstract Four new 2D honeycomb anilato-based ferrimagnets with Mn(II) and Cr(III) have been prepared and characterized. These compounds, formulated as (NBu4)[MnCr(C6O4X2)3(PhCHO)]·PhY (X/Y = Cl/H (1), Br/H (2), Cl/CHO (3) and Br/CHO (4) show that it is possible to include benzaldehyde as a co-ligand coordinated to the Mn(II) metal atom in these 2D ferrimagnets. This inclusion increases the coordination number of Mn(II) to seven resulting in a change in the ordering temperatures of these 2D ferrimagnets (from ca. 10–11 K to ca. 7 K). Here we show the role played by the additional benzaldehyde ligand and by the crystallization solvent molecules (benzene in 1 and 2 and benzaldehyde in 3 and 4) in the magnetic properties. Compounds 1–4 constitute a unique series of 2D magnets where the ordering temperature can be triply-modulated (with a ligand, a solvent and the X group of the anilato ligand).
