In the title compound, [Pb(C(7)H(4)FO(2))(2)(C(12)H(8)N(2))(2)]·2H(2)O, the Pb(II) atom is coordinated by four N atoms from two bidentate chelating 1,10-phenanthroline (phen) ligands and four O atoms from two 2-fluoro-benzoate ligands in an irregular polyhedral coordination geometry. Two carboxyl-ate O atoms and one F atom are each disordered over two sites with occupancy factors of 0.60 and 0.40. The dihedral angle between the two phen ligands is 89.9 (1)°. The mean inter-planar distances are alternatively of 3.44 (3) and 3.45 (3) Å, indicating π-π stacking inter-actions between the neighboring phen ligands. In the crystal, O-H⋯O, O-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]·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原子和来自两个2 - 氟苯甲酸酯配体的四个O原子以不规则多面体配位几何构型配位。两个羧酸根O原子和一个F原子各自在两个位置上无序分布，占据因子分别为0.60和0.40。两个phen配体之间的二面角为89.9 (1)°。平均平面间距离交替为3.44 (3) 和3.45 (3) 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、O - 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。
