n, the six-coordinate Pb
II ion is chelated by two 4-ethylbenzoate (PEB) anions and is bridged by two nicotinamide (NA) ligands, forming a polymeric chain running along the
b axis. The carboxylate groups of the PEB ions are twisted away from the attached benzene rings by 4.0 (6) and 13.3 (5)°. The two benzene rings of the PEB ions bonded to the same metal ion are oriented at a dihedral angle of 87.4 (3)°. In the polymeric chain, the NA ligand is linked to one of the carboxylate groups
via N—H
O hydrogen bonding. In the crystal, adjacent polymeric chains interact
via N—H

O hydrogen bonding. π–π stacking between the benzene and the pyridine rings [centroid–centroid distance = 3.805 (5) Å] and weak C—H

The title compound was prepared by the reaction of Pb(NO3)2 (1.656 g, 5 mmol) in H2O (100 ml) and nicotinamide (1.220 g, 10 mmol) in H2O (50 ml)
with sodium 4-ethylbenzoate (1.720 g, 10 mmol) in H2O (100 ml). The mixture
was filtered and set aside to crystallize at ambient temperature for three
weeks, giving colorless single crystals.
Atoms H2A and H2B (for NH2) and H61 and H62 (for H2O) were located in a
difference Fourier map and refined isotropically. The C-bound H-atoms were
positioned geometrically with C—H = 0.93, 0.97 and 0.96 Å, for aromatic,
methylene and methyl H-atoms, respectively, and constrained to ride on their
parent atoms, with Uiso(H) = k × Ueq(C), where
k = 1.5 for methyl H-atoms and k = 1.2 for all other H-atoms. The highest
peak and deepest hole are located 0.94 and 0.90 Å, respectively, from Pb1.

Special details top
Geometry. All esds (except the esd in the dihedral angle between two l.s. planes)
are estimated using the full covariance matrix. The cell esds are taken
into account individually in the estimation of esds in distances, angles
and torsion angles; correlations between esds in cell parameters are only
used when they are defined by crystal symmetry. An approximate (isotropic)
treatment of cell esds is used for estimating esds involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and
goodness of fit S are based on F2, conventional R-factors R are based
on F, with F set to zero for negative F2. The threshold expression of
F2 > 2sigma(F2) is used only for calculating R-factors(gt) etc. and is
not relevant to the choice of reflections for refinement. R-factors based
on F2 are statistically about twice as large as those based on F, and R-
factors based on ALL data will be even larger. |

As a part of our ongoing investigation on transition metal complexes of nicotinamide (NA), one form of niacin (Krishnamachari, 1974), and/or the nicotinic acid derivative N,N-diethylnicotinamide (DENA), an important respiratory stimulant (Bigoli et al., 1972), the title compound was synthesized and its crystal structure is reported herein.
In the crystal structure of the title compound, each PbII ion is coordinated by two 4-ethylbenzoate (PEB) and one nicotinamide (NA) ligands (Fig. 1), while symmetry related NA ligands bridge the PbII ions forming polymeric chains along the b axis (Fig. 2). The two PEB ions act as bidentate ligands, while the NA is monodentate ligand (Fig. 1). The crystal structures of similar complexes of CdII, CoII, MnII, ZnII and PbII ions, [Cd(C8H5O3)2(C6H6N2O)2(H2O)].H2O, (II) (Hökelek et al., 2009a), [Co(C9H10NO2)2(C6H6N2O)(H2O)2], (III) (Hökelek et al., 2009b), [Mn(C9H10NO2)2(C6H6N2O)(H2O)2], (IV) (Hökelek et al., 2009c), [Zn2(DENA)2(C7H5O3)4].2H2O, (V) (Hökelek & Necefoğlu, 1996), [Zn(C8H8NO2)2(C6H6N2O)2].H2O, (VI) (Hökelek et al., 2009d) and [Pb(C8H7O2)2(C6H6N2O)]n, (VII) (Hökelek et al., 2010), have also been reported. In (II) and (VII), the two benzoate ions are coordinated to the Cd and Pb atoms, respectively, as bidentate ligands. In the other structures one of the benzoate ligands acts as a bidentate ligand, while the other is monodentate ligand.
The average Pb—O bond length (Table 1) is 2.525 (5) Å and the Pb1 atom is displaced out of the least-squares planes of the carboxylate groups (O1/C1/O2) and (O3/C10/O4) by 0.1782 (3) Å and 0.3574 (3) Å, respectively. The O1/C1/O2 and O3/C9/O4 carboxylate planes form dihedral angles of 4.01 (63)° and 13.32 (53)°, respectively, with benzene rings A(C2-C7) and B(C11-C16), while the angles between rings A, B and C (N1/C19-C23) are A/B = 87.36 (26), A/C = 8.95 (22) and B/C = 78.76 (20)°. One of the intramolecular N-H···O hydrogen bonds (Table 2) links the NA ligand to the uncoordinated water molecule, while the other N-H···O hydrogen bond links the NA ligand to one of the carboxylate groups of the PEB ions acting as a bidentate ligand. In (I), the O1-Pb1-O2 and O3-Pb1-O4 angles are 51.10 (15)° and 51.95 (16)°, respectively. The corresponding O-M-O (where M is a metal) angles are 52.91 (4)° and 53.96 (4)° in (II), 60.70 (4)° in (III), 58.45 (9)° in (IV), 58.3 (3)° in (V), 60.03 (6)° in (VI), 51.09 (6)° and 51.71 (5)° in (VII) and 55.2 (1)° in [Cu(Asp)2(py)2] (where Asp is acetylsalicylate and py is pyridine) [(VIII); Greenaway et al., 1984].
In the crystal structure, N—H···O, O—H···O and C—H···O hydrogen bonds (Table 2) link adjacent chains into a two-dimensional network parallel to the bc plane. The π···π contact between the benzene and pyridine rings, Cg1—Cg3i, [symmetry code: (i) -x, -y, 1 - z, where Cg1 and Cg3 are the centroids of the rings A(C2-C7) and C (N1/C19-C23), respectively, may further stabilize the structure, with centroid-centroid distance of 3.805 (5) Å. There also exists a weak C—H···π interaction involving the benzene ring B(C11-C16) (Table 2).
