(E)-Methyl N'-(4-bromo-benzyl-idene)-hydrazinecarboxyl-ate at 123 K.

Rong Sun1, Xiang-Wei Cheng.   

Abstract

The title compound, C(9)H(9)BrN(2)O(2), crystallizes with two independent but essentially identical mol-ecules in the asymmetric unit. Each mol-ecule adopts a trans configuration with respect to the C=N bond. In one of the mol-ecules, the dihedral angle between the benzene ring and the n class="Chemical">hydrazinecarboxylic acid plane is 24.9 (2)°, and that in the other mol-ecule is 16.1 (2)°. The mol-ecules are linked into a three-dimensional network via inter-molecular N-H⋯O, C-H⋯O, C-H⋯N and C-H⋯Br hydrogen bonds. An intramolecular N-H⋯O hydrogen bond is also present.

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.
