In the title compound, [Pb(C(7)H(4)FO(2))(2)(C(12)H(8)N(2))(2)(H(2)O)(0.5)]·2H(2)O, the Pb(II) atom is coordinated by four N atoms from two bidentate chelating 1,10-phenanthroline (phen) ligands, four O atoms from two 2-fluoro-benzoate ligands and a half-occupied water mol-ecule in an irregular coordination geometry. One carboxyl-ate O atom and two F atoms are each disordered over two sites with occupancy factors of 0.558 (6) and 0.442 (6). The two crystallographically independent phen ligands are co-planar [dihedral angle 0.0 (2)°]. Centroid-centroid distances of 3.659 (7) and 3.687 (7) Å indicate π-π stacking inter-actions between neighboring phen ligands. In the crystal, O-H⋯O, C-H⋯F and C-H⋯O hydrogen bonds link the complex mol-ecules and uncoordinated water mol-ecules into a supra-molecular network.
在标题化合物[Pb(C₇H₄FO₂)₂(C₁₂H₈N₂)₂(H₂O)₀.₅]·2H₂O中，Pb(II)原子由来自两个双齿螯合1,10 - 菲咯啉（phen）配体的四个N原子、来自两个2 - 氟苯甲酸酯配体的四个O原子以及一个占据率为一半的水分子以不规则配位几何构型配位。一个羧酸根O原子和两个F原子各自在两个位置上无序，占据因子分别为0.558 (6)和0.442 (6)。两个晶体学独立的phen配体共面[二面角为0.0 (2)°]。质心 - 质心距离为3.659 (7) Å和3.687 (7) Å，表明相邻phen配体之间存在π - π堆积相互作用。在晶体中，O - H⋯O、C - H⋯F和C - H⋯O氢键将配合物分子和未配位的水分子连接成一个超分子网络。
