In the title ZnII complex, [Zn(C8H8NO2)2(C6H6N2O)2]·H2O, the Zn atom is coordinated by two 4-methylaminobenzoate (MAB) and two isonicotinamide (INA) ligands in a distorted trigonal-bipyramidal geometry; one of the MAB ions acts as a bidentate ligand while the other MAB and the two INA are monodentate ligands. The dihedral angles between the carboxyl groups and the adjacent benzene rings are 8.52 (22) and 5.10 (14)°. In the crystal, intermolecular O—H⋯O and N—H⋯O hydrogen bonding links the molecules into a supramolecular structure. Weak intermolecular C—H⋯O interactions are also present.

The title compound was prepared by the reaction of ZnSO4.H2O (0.9 g, 5 mmol) in H2O (30 ml) and INA (1.22 g, 10 mmol) in H2O (20 ml) with sodium 4-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 yellow single crystals.
Atoms H71 and H72 (for H2O) were located in difference Fourier map and refined isotropically, with restrains of O7—H71 = 0.88 (4), O7—H72 = 0.88 (5) Å and H71—O7—H72 = 106 (4)°. The remaining H atoms were positioned geometrically with N—H = 0.86 Å (for NH and NH2) and C—H = 0.93 and 0.96 Å for aromatic and methyl H atoms 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.
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.The title compound, (I), is a monomeric complex, where the ZnII ion is surrounded by two methylaminobenzoate (MAB) and two isonicotinamide (INA) ligands. One of the MAB ions acts as a bidentate ligand, while the other MAB and two INA are monodentate ligands. The structures of similar complexes of ZnII ion, [Zn2(C10H14N2O)2(C7H5O3)4].2H2O, (II) (Hökelek & Necefoğlu, 1996) and [Zn(C9H10NO2)2(C6H6N2O)(H2O)2], (III) (Hökelek et al., 2009) have also been determined.
In the title compound (Fig. 1), the average Zn—O bond length (Table 1) is 2.095 (2) Å and the Zn atom is displaced out of the least-squares planes of the carboxylate groups (O1/C1/O2) and (O3/C8/O4) by 0.0717 (3) Å and 0.2813 (3) Å, respectively. The dihedral angle between the planar carboxylate groups and the adjacent benzene rings A (C2—C7) and B (C9—C14) are 8.52 (22)° and 5.10 (14)°, respectively, while those between rings A, B, C (N1/C15—C19) and D (N2/C20—C24) are A/B = 71.82 (7), A/C = 14.44 (6), A/D = 84.05 (8), B/C = 72.21 (7), B/D = 47.00 (8) and C/D = 74.92 (7) °. The intramolecular O—H···O hydrogen bond (Table 2) links the water molecule to the carboxylate group (O1/C1/O2). In (I), the O1—Zn1—O2 angle is 59.02 (8)°. The corresponding O—M—O (where M is a metal) angles are 58.3 (3)° in (II), 60.03 (6)° in (III) and 55.2 (1)° in [Cu(Asp)2(py)2] (where Asp is acetylsalicylate and py is pyridine) [(IV); Greenaway et al., 1984].
In the
intramolecular O—H···O and intermolecular O—H···O, N—H···O and C—H···O hydrogen bonds (Table 2) link the molecules into a supramolecular structure, in which they may be effective in the stabilization of the structure.For niacin, see: Krishnamachari (1974) and for the nicotinic acid derivative N,N-diethylnicotinamide, see: Bigoli et al. (1972). For related structures, see: Greenaway et al. (1984); Hökelek & Necefoğlu (1996); Hökelek et al. (2009).

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. |

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, (I), is a monomeric complex, where the ZnII ion is surrounded by two methylaminobenzoate (MAB) and two isonicotinamide (INA) ligands. One of the MAB ions acts as a bidentate ligand, while the other MAB and two INA are monodentate ligands. The structures of similar complexes of ZnII ion, [Zn2(C10H14N2O)2(C7H5O3)4].2H2O, (II) (Hökelek & Necefoğlu, 1996) and [Zn(C9H10NO2)2(C6H6N2O)(H2O)2], (III) (Hökelek et al., 2009) have also been determined.
In the title compound (Fig. 1), the average Zn—O bond length (Table 1) is 2.095 (2) Å and the Zn atom is displaced out of the least-squares planes of the carboxylate groups (O1/C1/O2) and (O3/C8/O4) by 0.0717 (3) Å and 0.2813 (3) Å, respectively. The dihedral angle between the planar carboxylate groups and the adjacent benzene rings A (C2—C7) and B (C9—C14) are 8.52 (22)° and 5.10 (14)°, respectively, while those between rings A, B, C (N1/C15—C19) and D (N2/C20—C24) are A/B = 71.82 (7), A/C = 14.44 (6), A/D = 84.05 (8), B/C = 72.21 (7), B/D = 47.00 (8) and C/D = 74.92 (7) °. The intramolecular O—H···O hydrogen bond (Table 2) links the water molecule to the carboxylate group (O1/C1/O2). In (I), the O1—Zn1—O2 angle is 59.02 (8)°. The corresponding O—M—O (where M is a metal) angles are 58.3 (3)° in (II), 60.03 (6)° in (III) and 55.2 (1)° in [Cu(Asp)2(py)2] (where Asp is acetylsalicylate and py is pyridine) [(IV); Greenaway et al., 1984].
In the crystal structure, intramolecular O—H···O and intermolecular O—H···O, N—H···O and C—H···O hydrogen bonds (Table 2) link the molecules into a supramolecular structure, in which they may be effective in the stabilization of the structure.
