硒氰酸亚铜

硒氰酸亚铜是一种无机化合物，化学式为CuSeCN，难溶于水，溶度积为1.82×10-10（20℃）。A M Golub, Viktor V Skopenko. Metal Selenocyanates and Their Properties. Russian Chemical Reviews, 1965. 34 (12)CuSeCN存在α、β、γ、γ'、δ、ε等相。Tsetseris L.

制备
电化学法是以铜为阳极电解硒氰酸钾溶液，可以得到硒氰酸亚铜晶体：Paul A. Kilmartin, Graham A. Wright. Copper Selenocyanate Formation on the Copper Anode. Australian Journal of Chemistry, 1997. 50(4) 321 - 328. doi: 10.1071/C96110
 Cu + SeCN− − e− → CuSeCN

化学法是利用了氯化亚铜和硒氰酸钾的反应，反应物在丙酮中混合，加入少量水析出沉淀。用Na2S2O3处理硫酸铜溶液，接着加入硒氰酸钾，也能制得硫氰酸亚铜。Erik Soderback. Copper(I) selenocyanate. Acta Chemica Scandinavica (1947-1973), 1974. 28 (1): 115-117. ISSN: 0001-5393

性质
硒氰酸亚铜可以吸收氢气，形成CuSeCNH2。Tsetseris L. Two-dimensional cyanates: stabilization through hydrogenation[J]. Physical Chemistry Chemical Physics, 2016, 18(21):14662.
