The title compound, C(15)H(20)N(2)O(2) (2+)·2PF(6) (-), was prepared by anion exchange of two bromide ions in the ionic liquid 2,2'-bis-(pyridinium-1-ylmeth-yl)-propane-1,3-diol dibromide with potassium hexa-fluoro-phosphate. The two pyridine rings are planar (r.m.s. deviations = 0.008 and 0.00440 Å) and make a dihedral angle of 44.0 (2)°. Intermolecular O-H⋯F and C-H⋯F interactions occur. The four F atoms in each anion were refined as disordered over two sets of sites with an occupancy ration of 0.700 (19):0.300 (19).
标题化合物C(15)H(20)N(2)O(2)(2+)·2PF(6)(-)是通过离子液体2,2'-双-(吡啶-1-基甲基)-丙烷-1,3-二醇二溴化物中的两个溴离子与六氟磷酸钾进行阴离子交换制备的。两个吡啶环是平面的（均方根偏差分别为0.008和0.00440 Å），二面角为44.0(2)°。分子间存在O-H⋯F和C-H⋯F相互作用。每个阴离子中的四个F原子在两组位置上呈无序细化，占有率为0.700(19):0.300(19)。
