Tetra­kis[μ-4-(methyl­amino)­benzoato-κ2 O:O′]bis­[(N,N-diethyl­nicotinamide-N 1)zinc(II)] dihydrate

Abstract

The title mol­ecule, [Zn2(C8H8NO2)4(C10H14N2O)2]·2H2O, is a centrosymmetric binuclear complex, with two ZnII ions [Zn(...)Zn’ = 2.9301 (4) Å] bridged by four methyl­amino­benzoate (MAB) ligands. The four nearest O atoms around each ZnII ion form a distorted square-planar arrangement with the distorted square-pyramidal coordination completed by the pyridine N atom of the N,N-diethyl­nicotinamide (DENA) ligand. Each ZnII ion is displaced by 0.3519 (2) Å from the plane of the four O atoms, with an average Zn—O distance of 2.030 Å. The dihedral angles between carboxyl­ate groups and adjacent benzene rings are 10.57 (10) and 16.63 (12)°, while the benzene rings are oriented at a dihedral angle of 81.84 (5)°. The pyridine ring is oriented at dihedral angles of 40.49 (6) and 51.25 (6)° with respect to the benzene rings. In the crystal structure, inter­molecular O—H(...)O and N—H(...)O hydrogen bonds link the mol­ecules into a three-dimensional network. The π–π contact between the inversion-related pyridine rings [centroid–centroid distance = 3.633 (1) Å] may further stabilize the crystal structure.

Comment

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 title compound is a binuclear compound, consisting of two DENA and four methylaminobenzoate (MAB) ligands. The crystal structures of similar complexes of Cu2+ and Zn2+ ions, [Cu(C6H5COO)2(C5H5N)]2 (Usubaliev et al., 1980), [Cu(C6H5CO2)2(py)]2 (Speier & Fulop, 1989), [Cu2(C6H5COO)4(C10H14N2O)2] (Hökelek et al., 1995) and [Zn2(C11H14NO2)4(C10H14N2O)2] (Hökelek et al., 2009) have also been reported. In these structures, the benzoate ion acts as a bidentate ligand.

The title dimeric complex, [Zn2(MAB)4(DENA)2].H2O, has a centre of symmetry and the two ZnII ions are surrounded by four MAB groups and two DENA ligands. The DENA ligands are coordinated to ZnII ions through pyridine N atoms only. The MAB groups act as bridging ligands. The Zn···Zn' distance is 2.9301 (4) Å. The average Zn—O distance is 2.0297 (13) Å (Table 1), and four O atoms of the bridging MAB ligands around each ZnII ion form a distorted square plane. The ZnII ion lies 0.3519 (2) Å below the least-squares plane. The average O—Zn—O bond angle is 88.30 (6)°. A distorted square-pyramidal arrangement around each ZnII ion is completed by the pyridine N atom of DENA ligand at 2.0516 (14) Å (Table 1) from the Zn atom. The N1—Zn1···Zn1' angle is 159.67 (4)° and the dihedral angle between plane through atoms Zn1, O1, O2, C1, Zn1', O1', O2'and C1' and the plane through Zn1, O3, O4, C8, Zn1', O3', O4', and C8' atoms is 89.00 (7)°. The dihedral angles between the planar carboxylate groups and the adjacent benzene rings A (C2—C7) and B (C9—C14) are 10.57 (10)° and 16.63 (12)°, respectively, while that between rings A and B is A/B = 81.84 (5)°. Ring C (N1/C15-C19) is oriented with respect to rings A and B at dihedral angles A/C = 40.49 (6) and B/C = 51.25 (6) °.

In the crystal structure, intermolecular O—H···O and N—H···O interactions (Table 2) link the molecules into a three-dimensional network, in which they may be effective in the stabilization of the structure. The π–π contact between the pyridine rings, Cg1—Cg1i, [symmetry code (i): 2 - x, -y, 1 - z, where Cg1 is centroid of the ring C (N1/C15—C19)] may further stabilize the structure, with centroid-centroid distance of 3.633 (1) Å.

Experimental

The title compound was prepared by the reaction of ZnSO4.H2O (0.9 g, 5 mmol) in H2O (30 ml) and DENA (1.78 g, 10 mmol) in H2O (20 ml) with sodium p-methylaminobenzoate (1.74 g, 10 mmol) in H2O (50 ml). The mixture was filtered and set aside to crystallize at ambient temperature for one week, giving colourless single crystals.

Refinement

Atoms H61 and H62 (for H2O) were located in a difference Fourier map and refined isotropically. The remaining H atoms were positioned geometrically with N-H = 0.86 Å and 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) = xUeq(C,N), where x = 1.5 for methyl H and x = 1.2 for all other H atoms.

Special details

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s 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 > σ(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.
