<jats:title>Abstract</jats:title><jats:p>Ag4[Fe(CN)6]→Ag reduction process occurring in Ag4[Fe(CN)6]- gelatin-immobilized matrices, has been studied. In the course of reduction, these matrices are in a contact with water-alkaline solu-tion containing tin(II) dichloride along with an organic or inorganic compound capable of forming a stable soluble complex with Ag(I). It has been found that the substance formed in the gelatin matrix, is almost pure elemental silver, which consists two various phases which are distinguished by their optical and X-ray diffraction parameters. <jats:inline-formula><jats:alternatives><jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="graphic/s11532-009-0148-2_1.jpg" /></jats:alternatives></jats:inline-formula></jats:p>
