Potassium tartrate dibasic hemihydrate is the dipotassium salt of tartaric acid.

Potassium tartrate dibasic hemihydrate (Potassium L-tartrate dibasic hemihydrate) may be used in the hydrothermal synthesis of 4 metal-organic coordination polymers:

• {[Cd₃(C₄H₄O₆)₃(H₂O)].H₂O}_n
• {Cd₃(C₄H₃O₆)₂(H₂O)₂].5.5H₂O}_n
• {[Cd₂(C₄H₄O₆)₂(H₂O)].3H₂O}_n
• [Cd(C₄H₄O₆)]_n
