The reaction of 1,1,2,2-tetrakis­(4-(pyridin-4-yl)­phenyl)­ethene (tppe) with [Fe­(NCBH3)2] produced a two-dimensional coordination polymer [Fe­(NCBH3)2(tppe)]n (1), which was pillared in an ABAB manner through interlayer multiple [C–Hδ+···Hδ−–B] dihydrogen bonds (DHBs) to form a stable porous three-dimensional (3D) supramolecular structure that showed guest-molecule-dependent spin-crossover behaviors.
