The supramolecular compound [NEt~4][Mn(salophen) (H~2O)~2]~2[Fe(CN) ~6]·H~2O·CH~3OH [salophenH~2=N,N'-bis(salicylidene)-1,2- diaminobenzene] was synthesized by reacting [NEt~4][Fe(CN)~6] with [Mn(salophen)(CH~3OH)(H~2O)]ClO~4 at room temperature. Its structure was determined by X-ray analysis. The crystal belongs to triclinic system, space group P1, with unit cell dimensions a=1.2150(4) nm, b=1. 4834(6) nm, c=1.6625(6) nm, α=81.896(7)°,β=76.980(8)°, γ=81.120(6) °, V=2.872(2) nm^3, Z=2, D~c=1.388 g·cm^-^3. The network structure of the supramolecule is attributed to the hydrogen bonding in the compound. The results of thermal analysis, IR, UV-vis can also be explained by the structure data.
