Assembling Bi-, Tri- and Pentanuclear Complexes into Extended Structures Using a Desolvation Reaction: Synthesis, Structure, and Magnetic Properties of Manganese(III)−Schiff-Base−Hexacyanoferrate Polymeric Compounds and Their Derived Extended Structures

[Mn(BS)(H2O)]ClO4 and [NEt4]3[Fe(CN)6] react in methanol or ethanol to give a binuclear [NEt4]2[{Mn(BS)(S)}{Fe(CN)6}], 1, three trinuclear [NEt4][{Mn(BS)(S)}2{Fe(CN)6}], 2−4, and a pentanuclear [Mn(BS)(S)]4[Fe(CN)6]ClO4, 5, heterometal complex, depending on the nature of the quadridentate Schiff-base ligands and regardless of the stoichiometric ratio of the precursor components (BS = saldmen = N,N‘-(1,1-dimethylethylene)bis(salicylideneiminato) dianion, S = H2O for 1; BS = rac-salmen = rac-N,N‘-(1-methylethylene)bis(salicylideneiminato) dianion, S = MeOH for 2; BS = rac-salcy = rac-N,N‘-(1,2-cyclohexanediylethylene)bis(salicylideneiminato) dianion, S = MeOH for 3; (R,R)-salcy = (R,R)-N,N‘-(1,2-cyclohexanediylethylene)bis(salicylideneiminato) dianion, S = H2O for 4; BS = saltmen = N,N‘-(1,1,2,2-tetramethylethylene)bis(salycylideneiminato) dianion, S = H2O for 5). Complexes 1 and 2 have been characterized by X-ray analyses. Complex 1 consists of a discrete CN-bridged Mn(III)−Fe(III) binuclear unit [(H2O)Mn(...
