Гексацианоферра́ты (II) (ферроциани́ды, соли железистосинеродистой кислоты) — соединения, содержащие комплексный ион [Fe(CN)6]4−. Например, ферроцианид калия K4[Fe(CN)6] (желтая кровяная соль) применяется в аналитической химии (для определения Fe3+), а также для получения берлинской лазури.

Свойства

Анион очень прочен (его константа нестойкости, по разным данным[1][2], от 4⋅10−36 до 1⋅10−35), не разлагается ни щелочами, ни кислотами, устойчив по отношению к воздуху; поэтому растворы ферроцианидов не дают реакций ни на , ни на [1].
