In the title compound, [Zn4(C16H10N4O2)4]·4H2O, the N′-[(8-oxidoquinolin-7-yl)methyl­idene]isonicotinohydrazidate (L2−) ligand binds to the metal ions, forming stable five- and six-membered chelate rings, leaving the pyridyl groups free. The compound is a tetra­nuclear ZnII complex centered about a fourfold roto-inversion axis, with the ligand coordinating in the doubly deprotonated form. The ZnII atom has a distorted square-pyramidal geometry being coordinated by one N and two O-atom donors from the doubly deprotonated L2− ligand, and by one N atom and one O-atom donor from a symmetry-related L2− ligand. In the crystal, four symmetry-related lattice water mol­ecules, centred about a fourfold roto-inversion axis, form a cyclic tetra­mer through O—H⋯O hydrogen bonds. These tetra­mers connect to the complex mol­ecules through O—H⋯N hydrogen bonds, forming a chain propagating along [100]. Neighbouring mol­ecules are linked by π–π inter­actions [centroid–centroid distance = 3.660 (2) Å] involving the quinolidine rings.

Comment top

The synthesis of metal-containing compounds is the first and an important step in a promising route to novel heterometallic coordination polymers (Tao et al., 2002). It is well known that the relative orientations of N donors and the variation of the bridging spacer may lead to the construction of supramolecular motifs that have not been achieved using normal linear organic ligands. The ligand N'-((8-hydroxyquinolin-7-yl)methylene)isonicotinohydrazide ligand (LH2) is unsymmetrical, containing two different terminal coordinating sites, i.e. a pyridyl and a 7-hydrazinylidene-8-hydroxyquinoline chelator. The latter contains the N/O-bidentate chelating motif, which usually binds to metal ions in a deprotonated manner (Palacios et al., 2008). It was also found that this chelator binds to metal ions in preference to the pyridine N atom. This could provide a favourable coordination strategy for the synthesis of multinuclear metal-containing compounds. As part of our continuing studies of coordination compounds with bridging N-donor ligands (Dong et al., 2005), we report herein on the synthesis and crystal structure of a novel ZnII compound with free pyridyl groups.

The title compound is a tetranuclear ZnII complex, centred about a fourfold roto-inversion axis, and crystallizes as a tetrahydrate (Fig. 1). The ZnII atom has distorted square-pyramidal geometry, being coordinated by one N (N2) and two O donors (O1 and O2) from a doubly deprotonated LH2 ligand, and one N (N1i) and one O donor (O2i) from a symmetry-related L2- ligand [symmetry code :(i) -y + 5/4, x - 3/4, -z + 9/4]. The N atoms of the pyridine rings are not involved in coordination. The dihedral angle between the pyridine and quinoline ring mean planes is 14.01 (15)°. The Zn—N distances are 2.081 (2) for N1i and 2.036 (2) Å for N2, which are consistent with values reported previously (Kumar et al., 2006). The Zn—O bond lengths, 2.0329 (19) Å for O1, 2.0350 (18) Å for O2i and 2.0604 (18) Å for O2, are very close to the Zn—O bond lengths reported by (Woodward et al., 2006).

In the crystal, four symmetry-related lattice water molecules form a cyclic tetramer through O—H···O hydrogen bonds (Fig. 2 and Table 1). These water tetramers are linked to the complex molecules through O—H···N hydrogen bonds (Table 1), so forming a one-dimensional chain propagating parallel to the [001] direction. Parallel chains are connected by π-π interactions involving rings (C4—C9) and (N1/C1—C5)ii [centroid-to-centroid distance 3.660 (2) Å; symmetry code: (iv) -x+2, -y+1, -z+2] resulting in the formation of a two-dimensional network (Fig. 3).

Experimental top

A solution of LH2 (5.3 mg,0.02 mmol) in MeOH (8 ml) was layered onto a solution of ZnSO4 (5.8 mg, 0.04 mmol) in water (8 mL). The system was left for about two weeks at room temperature and yellow crystals of the title complex were obtained (yield 5.6 mg, 79%). Analysis, calc. for C64H48N16O12Zn4: C 51.43, H 3.24, N 14.99%; found: C 51.39, H 3.30, N 14.93%.

Refinement top

The C-bound H atoms were placed in geometrically idealized positions and included as riding atoms: C—H = 0.93 Å and Uiso(H) = 1.2Ueq(C). The water H atoms were located in a difference Fourier maps and refined with distance O—H restrained to 0.85 (2) Å and Uiso(H) = 1.2Ueq(O)

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.
