(de) Lead(II) thiocyanate is a compound, more precisely a salt, with the formula Pb(SCN)2. It is a white crystalline solid, but will turn yellow upon exposure to light. It is slightly soluble in water and can be converted to a basic salt (Pb(CNS)2·Pb(OH)2 when boiled. Salt crystals may form upon cooling. Lead thiocyanate can cause lead poisoning if ingested and can adversely react with many substances. It has use in small explosives, matches, and dyeing. Lead(II) thiocyanate is reasonably soluble at room temperature, thus it may be difficult to identify in a solution with low concentration of lead(II) thiocyanate. Although it has not been confirmed by other sources than the author of this article, experiments show that even if there is no precipitation of lead(II) thiocyanate in the solution, crystals of the salt may form. (en) Le thiocyanate de plomb(II) de formule semi-développée Pb(SCN)2 est un composé inorganique. Il s'agit du sel d'un ion plomb2+ avec deux anions thiocyanate, SCN−. Le thiocyanate de plomb(II) peut être préparé par métathèse avec de l'acétate de plomb(II) dissous dans l'eau et du thiocyanate de potassium, KSCN ou d'ammonium, NH4SCN, provoquant ainsi la précipitation du thiocyanate de plomb : Pb2+(aq) + 2 SCN−(aq) → Pb(SCN)2(s) Cependant, le thiocyanate de plomb(II) étant raisonnablement soluble (ce qui explique aussi sa toxicité), il peut être difficile de le faire précipiter (et donc de l'identifier) dans des solutions faiblement concentrées. Il semble toutefois que des solutions sans précipité et de concentration borderline puissent former des cristaux de thiocyanate de plomb(II).[réf. souhaitée] (fr) チオシアン酸鉛(II)（英: lead(II) thiocyanate）は二価の鉛のチオシアン酸塩で、化学式Pb(SCN)2で表される無機化合物。 (ja) Lood(II)thiocyanaat is het loodzout van thiocyaanzuur en heeft als brutoformule Pb(SCN)2.
