title: Butane-1,2,3,4-tetra-carb-oxy-lic acid-1,10-phenanthroline-water (1/2/2).
abstract: The asymmetric unit of the title compound, 2C(12)H(8)N(2)·C(8)H(10)O(8)·2H(2)O, contains one 1,10-phenanthroline mol-ecule, one half-mol-ecule of butane-1,2,3,4-tetra-carb-oxy-lic acid (H(4)BTC) and a water mol-ecule, with the complete tetra-acid generated by crystallographic inversion symmetry. Inter-molecular O-H⋯O hydrogen bonds and π-π stacking inter-actions [centroid-centroid distances = 3.672 (2) and 3.708 (2) Å form an extensive three-dimensional network, which consolidates the crystal packing.
