4,4'-[8b,8c-Bis(ethoxycarbonyl)-4,8-dioxo-2,3,5,6-tetra-hydro-1H,4H-2,3a,4a,6,7a,8a-hexa-azacyclo-penta-[def]fluorene-2,6-diyl]dipyridinium bis-(tetra-fluorido-borate).

ABSTRACT: In the title compound, C(26)H(32)N(8)O(6) (2+)·2BF(4) (-), the cation is built up from four fused rings, viz. two nearly planar imidazole rings and two triazine rings exhibiting chair conformations. One eth-oxy group is disordered between two positions in an approximate ratio 3:2. The F atoms of the two anions are each rotationally disordered between two orientations in the same 3:2 ratio. The crystal structure is stabilized by inter-molecular N-H⋯O, C-H⋯F and N-H⋯F inter-actions.
