'''硫氰酸锌'''（化学式：Zn(NCS)<sub>2</sub>，又称'''异硫氰酸锌'''）是[[锌]]的[[硫氰酸盐]]。

==性质==
硫氰酸锌是一种白色易吸潮的固体，溶于水和[[乙醇]]，并容易生成 <math>\rm \ [Zn(NCS)_4]^{2-}</math> 配离子。

==制取==
由[[硫酸锌]]和[[硫氰酸钡]]溶液混合，过滤并蒸发溶液至干而得。<ref>{{锌分族|page=715}}</ref>
:<math>\rm \ ZnSO_4+Ba(SCN)_2\rightarrow BaSO_4\downarrow +Zn(SCN)_2</math>
其二水合物可由[[硝酸锌]]和[[硫氰酸铵]]在水溶液中反应得到。[[氢氧化钡]]会降低其溶解度，使之易于结晶。<ref>{{cite journal|url=http://www.cnki.net/kcms/doi/10.16553/j.cnki.issn1000-985x.1991.02.002.html|title=二水异硫氰酸锌单晶生长及其非线性光学性能 - 中国学术期刊网络出版总库|accessdate=2018-10-30|doi=10.16553/j.cnki.issn1000-985x.1991.02.002}}</ref>
