N2  - The asymmetric unit of the title compound, [K(C5HF6N2)(H2O)2]n, is composed of two 3,5-bis­(trifluoro­meth­yl)pyrazol­ide anions, two potassium cations and four water mol­ecules. The water mol­ecules and 3,5-bis­(trifluoro­meth­yl)pyrazolide anions act as bridges between the potassium cations. Each potassium cation is surrounded by four O atoms [K—O = 2.705 (3)–2.767 (3) Å] and four F atoms [K—F = 2.870 (7)–3.215 (13) Å]. The water mol­ecules and the 3,5-bis­(trifluoro­meth­yl)pyrazolide anions are connected by O—H ... N hydrogen bonds, forming layers in the ab plane. All –CF3 groups show rotational disorder between two orientations each.
