In the last three decades, research has accelerated, as it has emerged that creating bridging systems based on cyanido ligands is a good and relatively simple way to create complex polymer structures exhibiting magnetic properties. Based on many years of personal experience in the field of the synthesis of polycyanido systems, supported by comprehensive structural analysis, a simple method of transforming cyanido complexes into soft ferromagnetic materials with a Curie temperature (TC) higher than the thermal decomposition temperature, usually above 150 \u00b0C has been developed. Two soft ferromagnetic materials based on zinc and cadmium hexacyanido salts in the system with [W(CN)6(bpy)]2\u2212\/\u2212 anions are presented. The crystal structures (X-ray single crystal as well as XRD) of the precursors and the properties of the ferromagnetic materials are discussed. Most importantly, a patented method of synthesizing this type of material, based on which we obtain more than 80 soft, high-temperature ferromagnetic compounds, which proves the wide spectrum of this method, is also presented.<\/jats:p>","DOI":"10.3390\/molecules27144525","type":"journal-article","created":{"date-parts":[[2022,7,18]],"date-time":"2022-07-18T01:53:22Z","timestamp":1658109202000},"page":"4525","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["The High-Temperature Soft Ferromagnetic Molecular Materials Based on [W(CN)6(bpy)]2\u2212\/\u2212 System"],"prefix":"10.3390","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9747-9238","authenticated-orcid":false,"given":"Janusz","family":"Szklarzewicz","sequence":"first","affiliation":[{"name":"Faculty of Chemistry, Jagiellonian University, 30-387 Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maciej","family":"Hodorowicz","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, Jagiellonian University, 30-387 Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Jurowska","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, Jagiellonian University, 30-387 Krak\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stanis\u0142aw","family":"Baran","sequence":"additional","affiliation":[{"name":"M.
