The title compound, D-(+)-glucosammonium potassium tetrathiocyanatocobaltate(II) dihydrate, K(C6H14NO5)[Co(NCS)4]·2H2O or (GlcNH)(K)[Co(NCS)4]·2H2O, has been obtained as a side product of an incomplete salt metathesis reaction of D-(+)-glucosamine hydrochloride (GlcN·HCl) and K2[Co(NCS)4]. The asymmetric unit contains a D-(+)-glucosammonium cation, a potassium cation, a tetraisothiocyanatocobalt(II) complex anion and two water molecules. The water molecules coordinate to the potassium cation, which is further coordinated via three short K+...SCN− contacts involving three [Co(NCS)4]2− complex anions and via three O atoms of two D-(+)-glucosammonium cations, leading to an overall eightfold coordination around the potassium cation. Hydrogen-bonding interactions between the building blocks consolidate the three-dimensional arrangement.
