The asymmetric unit of the title compound, [K(C(3)H(3)N(2))(C(12)H(24)O(6))], is composed of a potassium cation bonded to the six O atoms of a crown ether mol-ecule and the two N atoms of a pyrazolate anion. The K⋯O distances range from 2.8416 (8) to 3.0025 (8) Å, and the two K⋯N distances are 2.7441 (11) and 2.7654 (11) Å. The K cation is displaced by 0.8437 (4) Å from the best plane through the six O atoms. The latter plane is almost perpendicular to the plane of the pyrazolate ring [dihedral angle 83.93 (3)°].
标题化合物[K(C₃H₃N₂)(C₁₂H₂₄O₆)]的不对称单元由一个钾阳离子与一个冠醚分子的六个O原子以及一个吡唑阴离子的两个N原子键合而成。K⋯O距离在2.8416 (8)至3.0025 (8) Å之间，两个K⋯N距离分别为2.7441 (11)和2.7654 (11) Å。钾阳离子从通过六个O原子的最佳平面位移了0.8437 (4) Å。后一个平面几乎垂直于吡唑环的平面[二面角83.93 (3)°]。
