(Received 10 February 2013; accepted 18 February 2013; online 23 February 2013)

In the title complex, [Zn(N3)2(C7H10N2)2], the ZnII atom is coordinated by two N atoms from two 4-(dimethyl­amino)­pyridine (DMAP) ligands and by two N atoms from two azide anions in a distorted tetra­hedral coordination geometry. In the crystal, weak C—H⋯N hydrogen bonds between the DMAP and azide ligands link these discrete complex mol­ecules into a three-dimensional supra­molecular network.

Comment top

Pyridine derivatives are an important class of ligand for constructing metal-organic frameworks. 4-Dimethylaminopyridine (DMAP) has good coordination ability, but there are few reports on its complexes (Tyrra et al., 2003) except a lot of reports on its nucleophilic properties (Fu et al., 2000). The DMAP complexes which exhibit luminescence properties were reported (Araki et al., 2005). In our systematic studies on transition metal complexes with the pyridine derivatives and other ligands, the title compound [Zn(C7H10N2)2(N3)2] was prepared and its X-ray structure is presented here.

The title complex (I), is a mononuclear Zn(II) complex, consisting of two 4-dimethylaminopyridine (DMAP) ligands and two azide anions (Figure 1), all ligands coordinating in a monodentate manner. The title compound exhibits a distorted tetrahedral coordination involving two N atoms from two 4-dimethylaminopyridine (DMAP) ligands at 2.031 (2), 2.018 (2) Å and two N atoms from two azide anions at 1.934 (3), 1.968 (2) Å, all coordinated in a monodentate fashion (Figure 1). The bond angles around Zn atom vary from 103.45 (13) to 127.06 (11)°.

The crystal structure can be described as double layers which stack along the b axis, at c = 1/4 and 3/4, where each layer is formed of pairs of monomers (Figure 2). In the structure of (I), mononuclear units are held together with weak intermolecular C—H···N hydrogen bonds between the 4-dimethylaminopyridine and the azide, forming an alternating centrosymmetric rings in two-dimensional network which can be described by the graph-set motif R22(12) and R66(44) (Bernstein et al., 1995) (Figure 3). The combination of the four intermolecular C—H···N hydrogen bonds generates a three-dimensional network.

Experimental top

The title compound is prepared by reaction of methanolic solution containing Zn(CH3COO)2.2H2O, NaN3 and 4-dimethylaminopyridine in a 1:1:1 stoichiometric ratio. The solution was maintained in 293 K under agitation during one hour. Colorless crystals were appeared by evaporation of the solution at room temperature over the course of a few days.

Refinement top

The H atoms were placed at calculated positions with C—H = 0.93 and 0.96 Å, for aromatic and methyl H atoms, respectively, and refined in riding mode with Uiso(H) = 1.2Ueq(C) for aromatic H atoms and 1.5Ueq(C) for methyl H atoms.

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

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.
