Abstract: In the title compound, [Fe(C₁₂H₈N₂)₃](C₄O₄)·8H₂O or [Fe(phen)₃]sq·8H₂O, where phen is 1,10-phenanthroline and sq is the squarate dianion (C₄O₄)^2-, the Fe^II centre has a distorted octahedral coordination geometry comprising six N atoms from the three bidentate chelating phen ligands. An extensive three-dimensional network of O_water-HO, O_water-HO_water and C-HO hydrogen-bonding interactions is responsible for crystal stabilization.
