The asymmetric unit of the title compound, 2C12H8N2·C8H10O8·2H2O, contains one 1,10-phenanthroline mol­ecule, one half-mol­ecule of butane-1,2,3,4-tetra­carb­oxy­lic acid (H4BTC) and a water mol­ecule, with the complete tetra-acid generated by crystallographic inversion symmetry. Inter­molecular O—H⋯O hydrogen bonds and π–π stacking inter­actions [centroid–centroid distances = 3.672 (2) and 3.708 (2) Å form an extensive three-dimensional network, which consolidates the crystal packing.
