Ethyl (3E)-3-[2-(4-bromo-phenyl-sulfon-yl)hydrazin-1-yl-idene]butano-ate.


ABSTRACT: The asymmetric unit of title compound, C(12)H(15)BrN(2)O(4)S, contains two mol-ecules (A and B), with slightly different conformations: the bromo-phenyl rings and the SO(2) planes of the sulfonyl groups are oriented at dihedral angles of 50.2?(2) (mol-ecule A) and 58.24?(7)° (mol-ecule B), and the ethyl acetate groups make dihedral angles of 63.99?(19)° (A) and 65.35?(16)° (B) with their bromo-phenyl groups. In the crystal, both mol-ecules exist as inversion dimers linked by pairs of N-H?O hydrogen bonds, which generate R(2) (2)(14) loops. The dimers are linked by C-H?O inter-actions.
