Source of materials

A solution of Pb(CH3COOH)2 ⋅ 3H2O (0.1902 g, 0.5 mmol) in distilled water (5 mL) was added to a solution of 1,10-phenanthroline (C12H8N2, 0.0906 g, 0.5 mmol) and 4-hydroxybenzoate acid (0.1392 g, 1 mmol) in ethanol/water (v:v = 1:1, 20 mL). The mixture was stirred at 323 K and refluxed for 6 h and then a white precipitate was filtered. Bright colorless single crystals were obtained by slow evaporation of the filtrate after 3 d at room temperature, one of which was selected for an X-ray experiment.

Experimental details

Hydrogen atoms bound to C were positioned geometrically and refined as riding atoms, with C—H = 0.93 Å. Hydroxy H atoms were refined in a similar manner, with O—H = 0.82 Å. Water H atoms were found according to the residual electron-density peaks around each water O atom and the directions of hydrogen bonds, and were then locked in position with O—H = 0.85 Å and included in the refinement with the SHELXL AFIX 3 command. Uiso(H) were set to Uiso(H) = 1.2Ueq(C or N) and Uiso(H) = 1.5Ueq(O), respectively.

Comment

The coordination chemistry of lead(II) with N and O donor ligands has been investigated in past decades as [5]. Because of its electronic configuration and size, Pb(II) exhibits various coordination numbers and geometries. A number of lead(II) complexes with different donor ligands has been synthesized and studied by X-ray crystallography [6], [7], [8], [9], [10].

The crystal structure of the title compound consists of dimeric units of Pb(C7H5O3)2(C12H6N2), related by a crystallographic inversion centre (the figure), and complemented by an uncoordinated water molecule. Each PbII cation is chelated by two N atoms of 1,10-phenanthroline with Pb—N distances of 2.531(2) Å and 2.589(3) Å, and five carbonyl O atoms from three 4-hydroxybenzoate anions. The 4-hydroxybenzoate groups coordinate to each PbII ion in two different ways. Two 4-hydroxybenzoate ions behave as chelating ligands to a Pb atom, two form bridges between the two Pb atoms. The five Pb—O distances are significantly different, as are the two Pb—N distances. The shortest Pb—O distance is 2.326(2) Å and the longest is 2.920(2) Å. The weak Pb—O bridging interactions form a centrosymmetric four-membered Pb2O2 quadrilateral with a Pb⋯Pb distance of 4.305(6) Å. Molecules are linked into a two-dimensional frameword by O—H⋯O hydrogen bonds. The packing is further stabilized by π–π interactions in the sequence of benzoate-phenanthroline-benzoate-phenanthroline of neighbouring molecules. The centroid-centroid distances between Cg1(C20-C25) and Cg2(N1/C1-C4/C12) [symmetry code: 1 − x, 1 − y, 1 − z] and between Cg3(N2/C10-C7/C11) [symmetry code: 1 − x, 1 − y, 1 − z] and Cg4(C20-C25) [symmetry code: x, 1 + y, z] are 3.521 Å and 3.613 Å, respectively. This combination of hydrogen bonds and π-π stacking interactions builds a three-dimensional network architecture.
