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. |

In the past five years, our work have been focused on the chemistry of tetrazole derivatives because of their multiple coordination modes as ligands to metal ions and for the construction of novel metal-organic frameworks (Wang et al., 2005; Xiong et al., 2002). We report here the crystal structure of the title compound, 5-(4-methyl-3-nitrophenyl)-2H-tetrazole, (Fig.1).
The benzene ring makes a dihedral angle of 38.27 (0.11) ° with the tetrazole ring owing to the C–C bond bridge which force the two rings to be twisted from each other. The bond distances and bond angles of the tetrazole rings are in the usual ranges (Wang et al., 2005; Arp et al. , 2000; Hu et al., 2007). The crystal packing is stabilized by N—H···N hydrogen bonds to form an infinite one-dimensional chain parallel to the a axis. (Table 1, Fig. 2).
