n, the Cd
II cation is chelated by two chlorobenzoate anions and coordinated by two
N,
N-diethylnicotinamide (DENA) ligands and one water molecule in a distorted NO
6 pentagonal–bipyramidal geometry. The Cd
II cations are bridged by the pyridine N atom and carbonyl O atom of the DENA ligand to form a polymeric chain running along the
b axis. Intermolecular O—H

O hydrogen bonds between coordinating water molecules and carboxylate groups link adjacent chains into layers parallel to the
bc plane. π–π contacts between benzene rings [shortest centroid–centroid distance = 3.912 (2) Å] further stabilizes the crystal structure. In the molecule, weak C—H

O hydrogen bonds occur between the pyridine ring and carboxylate groups; the dihedral angles between the carboxylate groups and adjacent benzene rings are 4.6 (3) and 12.8 (3)°, while the benzene rings are oriented at a dihedral angle of 1.89 (13)°.

The title compound was prepared by the reaction of CdSO4.8H2O (1.283 g,
5 mmol) in H2O (100 ml) and diethylnicotinamide (1.780 g, 10 mmol) in H2O
(10 ml) with sodium 3-chlorobenzoate (1.790 g, 10 mmol) in H2O (100 ml).
The mixture was filtered and set aside to crystallize at ambient temperature
for ten days, giving colorless single crystals.
Atoms H61 and H62 (for H2O) were located in a difference Fourier map and
were refined freely. 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.

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.
The structures of some DENA and/or NA complexes of the Cu2+, Zn2+ and Co2+ ions, [Cu2(C6H5COO)4(C10H14N2O)2] (Hökelek et al., 1995); [Cu2(C8H7O2)4(C6H6N2O)2] (Necefoğlu et al., 2010a); [Zn2(C11H14NO2)4(C10H14N2O)2] (Hökelek et al., 2009a); [Zn2(C8H8NO2)4(C10H14N2O)2].2H2O (Hökelek et al., 2009b); [Zn2(C9H10NO2)4(C10H14N2O)2] (Hökelek et al., 2009c); [Zn2(C8H7O2)4(C10H14N2O)2] (Necefoğlu et al., 2010b) and [Co2(C11H14NO2)4(C10H14N2O)2] (Hökelek et al., 2011) have also been determined. In these structures, the benzoate ion acts as a bidentate ligand.
The asymmetric unit of the title CdII complex, [Cd(CB)2(DENA)(H2O)]n, contains two 3-chlorobenzoate (CB), one N,N-diethylnicotinamide (DENA) ligands and one coordinated water molecule; the CB ions act as bidentate ligands (Fig. 1). The coordination number of the CdII ion is six. Intramolecular C—H···O hydrogen bonds (Fig. 1 and Table 2) link the DENA ligand to the carboxyl groups. The O1—Cd1—O2 and O3—Cd1—O4 angles are 53.75 (10)° and 54.23 (9) °, respectively. The corresponding O—M—O (where M is a , metal) angles are 53.50 (14)° in [Cu2(C8H5O3)4(C6H6N2O)4] (Sertçelik et al., 2013), 53.45 (4)° and 51.97 (4)° in [Cd(C7H5O3)2(C6H6NO)(H2O)2].2(H2O) (Çaylak Delibaş et al., 2013), 52.91 (4)° and 53.96 (4)° in [Cd(C8H5O3)2(C6H6N2O)2(H2O)].H2O (Hökelek et al., 2009d), 60.70 (4)° in [Co(C9H10NO2)2(C6H6N2O)(H2O)2] (Hökelek et al., 2009e), 58.45 (9)° in [Mn(C9H10NO2)2- (C6H6N2O)(H2O)2] (Hökelek et al., 2009f), 60.03 (6)° in [Zn(C8H8NO2)2(C6H6N2O)2].H2O (Hökelek et al., 2009g), 58.3 (3)° in [Zn2(C10H14N2O)2(C7H5O3)4].2H2O (Hökelek & Necefoğlu, 1996) and 55.2 (1)° in [Cu(Asp)2(py)2] (where Asp is acetylsalicylate and py is pyridine) (Greenaway et al., 1984). The dihedral angles between the planar carboxylate groups [(O1/O2/C1) and (O3/O4/C8)] and the adjacent benzene rings A (C2—C7) and B (C9—C14) are 4.56 (28)° and 12.84 (26)°, respectively, while that between rings A, B and C (N1/C15–C19) are A/B = 1.89 (13), A/C = 34.83 (13) and B/C = 35.13 (11) °.
In the crystal, the CdII ions [Cd1···Cd1a = 7.0161 (5) Å; symmetry code: (a) x, y - 1, z] are bridged by the N and O atoms of the DENA ligands forming polymeric chains running along the b-axis direction, where the coordination number of each CdII atom is seven within a CdO6N donor set (Fig. 2). The average Cd—O distance is 2.389 (3) Å (Table 1). The Cd atom lies 0.0972 (3) Å below and 0.0127 (3) Å above of the carboxylate groups [(O1/O2/C1) and (O3/O4/C8)], respectively. Strong intermolecular O—H···O hydrogen bonds (Table 2) between water molecules and carboxylate groups link the adjacent chains into layers parallel to the bc plane. π···π contacts between the benzene rings Cg1—Cg2i, [symmetry code: (i) 1 - x, 2 - y, - z, where Cg1 and Cg2 are the centroids of the rings A (C2—C7) and B (C9—C14), respectively] may further stabilize the structure, with centroid-centroid distance of 3.912 (2) Å.
