Abstract top

In the title compound, [Zn(C11H8N5O)(N3)]n, the Zn atom is hexacoordinated by five N atoms and one O atom in a distorted octahedral geometry. The chelating 5-(8-quinolyloxymethyl)tetrazolate ligands are approximately planar, with a dihedral angle of 3.6 (2)° between the quinoline and tetrazole planes. Adjacent Zn atoms are linked by two bridging azide ligands across a centre of inversion, and further coordination by one N atom of an adjacent tetrazole unit forms two-dimensional frameworks in (100). C-H...N interactions exist between ligands in neighbouring layers.

Comment top

As shown in Fig. 1, the Zn atom adopts a distorted octahedral coordination geometry, coordinated by one N atom and one O atom from 8-hydroxyquinoline, two N atoms from two different tetrazole groups and two N atoms from two bridging azide groups. Thus, 8-[(1H-tetrazol-5-yl)methoxy]quinoline acts as a tetradentate linker while the azide groups bridge between Zn atoms to form centrosymmetric rhombic units. Two-dimensional frameworks are formed in the (100) planes, and C—H···N interactions exist between ligands in neighbouring planes.

Experimental top

A mixture of quinolin-8-ol (1.45 g, 10 mmol), 1.38 g K2CO3, 30 ml acetone and 2-bromoacetonitrile (1.32 g,11 mmol) was refluxed overnight. After cooling, the resulting dark mixture was extracted with ether (30 ml) and the solvent was removed at reduced pressure to give a crude product. Recrystallization from ethanol gave the pure ligand 2-(quinolin-8-yloxy)acetonitrile as a white powder. A mixture of this ligand (0.037 g, 0.2 mmol), ZnCl2 (0.026 g, 0.2 mmol) and water (1 ml) was sealed in a glass tube and maintained at 383 K. Yellow crystals of the title compound suitable for X-ray analysis were obtained after 3 d.

Refinement top

H atoms were placed geometrically with C—H = 0.93 or 0.97 Å and allowed to ride during refinement with Uiso(H) = 1.2Ueq(C).

Special details top

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.
