[3][1] The structure of Cu(SCN)2 was determined via powder X-ray diffraction and consists of chains of Cu(NCS)2 linked together by weak Cu–S–Cu bonds into two-dimensional layers.

It can be considered a Jahn–Teller distorted analogue of the mercury thiocyanate structure-type.

[1] Copper(II) thiocyanate can be prepared from the reaction of concentrated solutions of copper(II) and a soluble thiocyanate salt in water, precipitating as a black powder.

[2][3] With rapid drying, pure Cu(SCN)2 can be isolated.

Reaction at lower concentrations and for longer periods of time generates instead copper(I) thiocyanate.
