A chiral complex, [Fe(HL)2](PF6)2 (1), where HL denotes 2-pyridylmethylidenehydrazono-4-(2-methylimidazolyl)methane, was prepared. X-ray structure analysis revealed that it crystallizes as a kryptoracemate of sesquihydrate chiral crystals in the orthorhombic noncentrosymmetric space group P212121 (Z = 8, Z鈥?= 2). Two diastereomeric cationic complexes with opposite configuration reside within the asymmetric unit. KBr pellets prepared using selected single crystals showed enantiomorphous circular dichroism patterns.
