Abstract
In the title complex, [Fe(C12H8N3O2)2]ClO4·CH3OH, the iron(III) ion is surrounded by two tridentate N-(2-pyridylcarbonyl)pyridine-2-carboximidate (bpca) ligands and exhibits a distorted octahedral coordination by six bpca N atoms. A classical O—H⋯O hydrogen bond exists between the methanol solvent molecule and the perchlorate anion. Magnetic susceptibility measurements indicated the complex to be in the low-spin state in the temperature range 5–400 K.
