Source of material

An ethanol (15 mL) solution of bis(2-benzimidazol-ylmethyl)amine (bbma, 0.055 g, 0.2 mmol) was added to a aqueous (10 mL) solution of Pb(NO3)2 (0.066 g, 0.2 mmol). An ethanol (25 mL) solution of sodium nicotinate (0.030 g, 0.2 mmol) was added to the resulting solution slowly. The mixture was stirred for 6 h and then filtered. Colorless crystals were obtained by slow evaporation of the filtrate after 14 days.

Experimental details

The crystal structures were solved by direct methods using the SHELXS program of the SHELXTL crystallographic software package (AFIX 137 option of the SHELXL-97 program). Non-hydrogen atoms were refined with anisotropic displacement parameters. The hydrogen atoms of organic ligands were generated geometrically and refined isotropically.

Discussion

Pb2+ as a heavy p-block metal ion has unique lone pair electron effects (with ns2np0 configuration), such as a large radius and flexible coordination [1]. The lead(II) complexes with multi-functional organic ligands have attracted considerable attention. Bis(benzimidazol-2-yl-methyl)amine (bbma) is a linear tridentate ligand with two aromatic benzimidazole side arms. It is widely used to prepare metal complexes. Some transition metal complexes of it have been studied. They exhibite mononuclear, dinuclear, trinuclear and 1-D structural features [2], [3], [4]. A new Pb(II) complex containing bis(benzimidazol-2-yl-methyl)amine (bbma) and nicotinate were synthesized and structurally characterized with the formula [Pb(bbma)(nic)(NO3)].

In the title complex, both crystallographically independent Pb(II) ions are seven-coordinated showing a N4O3 donor set with three N atoms from bbma, one nicotinate N atom and two O atoms from another nicotinate, and one O atom (O5) from nitrate anion (cf. the figure). Bbma as a tridentate ligand coordinates to Pb(II) with its two side arms nearly coplanar.

The nicotinate offers two carboxylate O atoms in bidentate chelating mode. The coordination geometry of Pb(II) can be described as a distorted square bipyramid geometry with the center of the chelating carboxylate oxygens O1 and O2 (O3 and O4) occupying one of the bipyramid axial vertices. The O atom (O5/O8) of nitrato ligand occupying another axial vertice. Each nicotinate ligand exhibits a bidentate chelating mode with two obviously different Pb1—O (primary) distances. d(Pb1 − O1) = 2.355(4) Å is shorter than d(Pb1 − O2) = 2.702(4) Å, suggesting one oxygen atom is strongly coordinated to the metal ion while the other is weaker. Of the three Pb1—O distances, Pb1—O5 of nitrate anion is the longest [d(Pb1 − O5) = 3.025(4) Å]. The equatorial plane is defined by two benzimidazolic-N1, N2 atoms of bbma, the amino nitrogen atom N4 and N6 atom of nicotinate. As shown in the figure, of the four Pb1—N (primary) distances, two N atoms from two aromatic benzimidazole side arms are nearly equal [d(Pb1 − N4) = 2.568(5) Å, d(Pb1 − N2) = 2.516(5) Å], while the amino nitrogen atom is slightly longer [d(Pb1 − N1) = 2.613(5) Å], Pb1 − N6 of nicotinate is the longest [d(Pb1 − N6) = 3.054(5) Å]. The distortion in the coordination conditions is reflected in the average bite angles of two carboxylate oxygen atoms O2—Pb1—O5 and O1—Pb1—O5 to be 148°. The equatorial bond angels are from 64.1(2)° to 134.5(1)° and the total is 359°, the O5—Pb1—N1, O5—Pb1—N2, O5—Pb1—N6 bite angles are 67.8(1)°, 74.5(1)°, 115.6(1)° respectively. The coordination geometry of the Pb2 atom is very similar. Adjacent complexes are linked by the weak interactions between nicotinate N atom (N6/N12) with Pb1/Pb2 to form one-dimensional chain structures. The adjacent 1D linear chains are also connected by intermolecular hydrogen bonds through benzimidazole NH of bbma and the oxygen atom of nitrate anion to form a 2D layer structure.
