The new compartmental proligand 4-bromo-3,5-bis{6-(2,2'-bipyridyl)}pyrazole (HL(Br)) was synthesized and shown to form robust [2 × 2] grid complexes [Fe(II)4L(Br)4]X4 with various counteranions (X(-) = PF6(-), ClO4(-), BF4(-), Br(-)). The grid [Fe(II)4L(Br)4](4+) is stable in solution and features two high-spin...
