Nickel(II) thiocyanate is a coordination polymer with formula Ni(SCN)2.

[1] The structure of Ni(SCN)2 was determined via single-crystal X-ray diffraction and consists of two-dimensional sheets held together through Van der Waals forces.

It belongs to mercury thiocyanate structure-type and can be considered a distorted form of the NiBr2 (CdI2) structure.

Each nickel is octahedrally coordinated by four sulfurs and two nitrogens.

After removal of the precipitated barium sulfate]], the solution is allowed to evaporate leaving microcrystalline Ni(SCN)2.
