In the title compound, [Pb(C8H7O2)2(C6H6N2O)]n, the PbII ion is coordinated by two 4-methylbenzoate (PMB) and one nicotinamide (NA) ligands while symmetry-related NA ligands bridge adjacent PbII ions, forming polymeric chains along the c axis. The carboxylate groups in the two PMB ions are twisted away from the attached benzene ring by 22.9 (2) and 4.6 (2)°. The two benzene rings of the PMB ions are oriented at a dihedral angle of 83.7 (1)°. In a polymeric chain, the NA ligands are linked to PMB ions through intramolecular N—H⋯O hydrogen bonds. In the adjacent polymeric chains interact via N—H⋯O and C—H⋯O hydrogen bonds, forming a two-dimensional network parallel to the bc plane.

The title compound was prepared by the reaction of Pb(NO3)2 (1.656 g, 5 mmol) in H2O (50 ml) and nicotinamide (1.220 g, 10 mmol) in H2O (10 ml) with sodium 4-methylbenzoate (1.580 g, 10 mmol) in H2O (160 ml). The mixture was filtered and set aside to crystallize at ambient temperature for four weeks, giving colourless single crystals.
Atoms H2A and H2B of the NH2 group were located in a difference Fourier map and refined isotropically. The remaining H atoms were positioned geometrically with C–H = 0.93 and 0.96 Å for aromatic and methyl H atoms, respectively, and constrained to ride on their parent atoms, with Uiso(H) = xUeq(C), where x = 1.5 for methyl H and x = 1.2 for aromatic H atoms. One low angle reflection (100) was partially obscured by the beam stop and was omitted from the
The highest peak and deepest hole are located 0.86 and 0.68 Å, respectively, from Pb1.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
is reported herein.In the
of the title compound, each PbII ion is coordinated by two 4-methylbenzoate (PMB) and one nicotinamide (NA) ligands (Fig. 1), while symmetry related NA ligands bridge the PbII ions forming polymeric chains along the c axis (Fig. 2). The two PMB ions act as bidentate ligands, while the NA is monodentate ligand (Fig. 1).

In (II), the two benzoate ions are coordinated to the Cd atom 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 2.5606 (18) Å and the Pb1 atom is displaced out of the least-squares planes of the carboxylate groups (O1/C1/O2) and (O3/C9/O4) by -0.096 (10) Å and 0.403 (10) Å, respectively. The O1/C1/O2 and O3/C9/O4 carboxylate planes form dihedral angles of 22.9 (2)° and 4.6 (2)°, respectively, with benzene rings A(C2-C7) and B(C10-C15), while the angles between rings A, B and C (N1/C17-C21) are A/B = 83.7 (1), A/C = 65.4 (1) and B/C = 20.9 (1)°. An intramolecular N—H···O hydrogen bond (Table 2) links the NA ligand to one of the carboxylate groups of the PMB ions acting as a bidentate ligand. In (I), the O1—Pb1—O2 and O3—Pb1—O4 angles are 51.09 (6)° and 51.71 (5)°, 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) and 55.2 (1)° in [Cu(Asp)2(py)2] (where Asp is acetylsalicylate and py is pyridine) [(VII); Greenaway et al., 1984].

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-methylbenzoate (PMB) and one nicotinamide (NA) ligands (Fig. 1), while symmetry related NA ligands bridge the PbII ions forming polymeric chains along the c axis (Fig. 2). The two PMB ions act as bidentate ligands, while the NA is monodentate ligand (Fig. 1). The crystal structures of similar complexes of CdII, CoII, MnII and ZnII 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) and [Zn(C8H8NO2)2(C6H6N2O)2].H2O, (VI) (Hökelek et al., 2009d) have also been reported. In (II), the two benzoate ions are coordinated to the Cd atom 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 2.5606 (18) Å and the Pb1 atom is displaced out of the least-squares planes of the carboxylate groups (O1/C1/O2) and (O3/C9/O4) by -0.096 (10) Å and 0.403 (10) Å, respectively. The O1/C1/O2 and O3/C9/O4 carboxylate planes form dihedral angles of 22.9 (2)° and 4.6 (2)°, respectively, with benzene rings A(C2-C7) and B(C10-C15), while the angles between rings A, B and C (N1/C17-C21) are A/B = 83.7 (1), A/C = 65.4 (1) and B/C = 20.9 (1)°. An intramolecular N—H···O hydrogen bond (Table 2) links the NA ligand to one of the carboxylate groups of the PMB ions acting as a bidentate ligand. In (I), the O1—Pb1—O2 and O3—Pb1—O4 angles are 51.09 (6)° and 51.71 (5)°, 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) and 55.2 (1)° in [Cu(Asp)2(py)2] (where Asp is acetylsalicylate and py is pyridine) [(VII); Greenaway et al., 1984].
In the crystal structure, N—H···O and C—H···O hydrogen bonds (Table 2) link adjacent chains into a two-dimensional network parallel to the bc plane (Fig.2).
