Abstract
The title complex, [Fe(C15H10ClN3)2](NO3)2·2H2O, has a six-coordinate iron(II) center balanced by two nitrate anions. The Fe atom lies on a twofold rotation axis. The complex exhibits an octahedral coordination configuration, where the dihedral angle between the two planar tridentate ligands is 92.4 (1)°. The crystal structure involves O—H⋯O hydrogen bonds.
