Quinoline-3-carbonitrile (1 mmol, 0.154 g), Zn(NO3)2.6H2O (0.5 mmol, 0.10 g) in water (10 ml). The mixture solution was stirred for 30 min at room temperature. The mixed solution were added to 15 ml sealed teflon-lined stainless steel vessels and the teflon-lined stainless steel vessels was left at 433 K vacuum case for 3 d under autogenous pressure. After cooled to room temperature, colourless crystals were obtained (yield: 80%, based on Zn).
All other H atoms were positioned geometrically and refined as riding, with C–H distances of 0.93 Å and Uiso(H) = 1.2 Ueq(C).
Organic nitriles ligands and their hydroxlyate derivatives (carboxylates) have been widely used for hydrothermal synthesis of coordination polymers (Lin, et al., 1998; Tong, et al., 2003). Notably, these kinds of ligand reactions, relatively straight forward in the context of reaction chemistry, have become an important approach in the crystal engineering of metal-organic frameworks exhibiting novel physical properties. In the title compound, (I), the quin-3 - c group evidently results from the hydrolysis of quinoline-3-carbonitrile. The quin-3 - c ligands used in this work exhibit bridging mode different from other quinoline derivatives (Odoko, et al., 2001; Okabe & Muranishi, 2003). To the best of our knowledge, this is the first isolated quin-3 - c coordination polymer.
There are one ZnII atom and two quin-3 - c ligands in the asymmetric unit. The ZnII atom has a tetrahedral environment formed by two N atoms [Co – N 2.097 (2) - 2.102 (2) Å] and two O atoms [Co – O 1.927 (2) - 1.963 (2) Å] belonging to for different quin-3 - c ligands. The quin-3 - c ion binds to zinc in a bridge mode, through the carboxylate O atom and the quinoline N atom. The carboxylato group is monodentate. Each ZnII atom is connected by four ditopic quin-3 - c ligands, which construct a two-dimensional layer parallel to the (100) plane (Fig. 2) and generate two-dimensional square grids based on the (4, 4) topology. The quinoline rings of quin-3 - c penetrating into the adjacent layers are parallel to each other, and face-to-face separations are about 3.59 (1) Å (the second quinoline rings symmetry code: x, y, 1 - z) indicating π···π interaction.

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. |

Organic nitriles ligands and their hydroxlyate derivatives (carboxylates) have been widely used for hydrothermal synthesis of coordination polymers (Lin, et al., 1998; Tong, et al., 2003). Notably, these kinds of ligand reactions, relatively straight forward in the context of reaction chemistry, have become an important approach in the crystal engineering of metal-organic frameworks exhibiting novel physical properties. In the title compound, (I), the quin-3 - c group evidently results from the hydrolysis of quinoline-3-carbonitrile. The quin-3 - c ligands used in this work exhibit bridging mode different from other quinoline derivatives (Odoko, et al., 2001; Okabe & Muranishi, 2003). To the best of our knowledge, this is the first isolated quin-3 - c coordination polymer.
There are one ZnII atom and two quin-3 - c ligands in the asymmetric unit. The ZnII atom has a tetrahedral environment formed by two N atoms [Co – N 2.097 (2) - 2.102 (2) Å] and two O atoms [Co – O 1.927 (2) - 1.963 (2) Å] belonging to for different quin-3 - c ligands. The quin-3 - c ion binds to zinc in a bridge mode, through the carboxylate O atom and the quinoline N atom. The carboxylato group is monodentate. Each ZnII atom is connected by four ditopic quin-3 - c ligands, which construct a two-dimensional layer parallel to the (100) plane (Fig. 2) and generate two-dimensional square grids based on the (4, 4) topology. The quinoline rings of quin-3 - c penetrating into the adjacent layers are parallel to each other, and face-to-face separations are about 3.59 (1) Å (the second quinoline rings symmetry code: x, y, 1 - z) indicating π···π interaction.
