In the title mol-ecular salt, C(18)H(24)N(4) (2+)·2PF(6) (-), the complete dication is generated by a crystallographic inversion centre. The central benzene ring makes a dihedral angle of 77.19 (9)° with each of the imidazole rings. In the crystal, C-H⋯F inter-actions link the cations and anions into layers lying parallel to the bc plane. The hexa-fluoro-phosphate anion is disordered over two sets of sites in a 0.520 (11):0.480 (11) ratio.
在标题分子盐C(18)H(24)N(4)(2+)·2PF(6)(-)中，完整的二价阳离子由一个晶体学反演中心产生。中心苯环与每个咪唑环的二面角为77.19 (9)°。在晶体中，C-H⋯F相互作用将阳离子和阴离子连接成平行于bc平面的层。六氟磷酸根阴离子在两组位置上无序，比例为0.520 (11):0.480 (11)。
