4-(4-Bromo-phenyl-hydrazono)-1-(5-bromo-pyrimidin-2-yl)-3-methyl-2-pyrazolin-5-one.


ABSTRACT: The asymmetric unit of the title compound, C(14)H(10)Br(2)N(6)O, contains two crystallographically independent mol-ecules. The pyrazole ring of one mol-ecule makes dihedral angles of 22.0?(3) and 3.5?(3)° with the pyrimidine and benzene rings, respectively; the corresponding values in the other mol-ecule are 9.2?(3) and 2.1?(3)°, respectively. The mol-ecules are linked by N-H?O, C-H?N and C-H?Br hydrogen bonds.

The asymmetric unit of the title compound, C(14)H(10)Br(2)N(6)O, contains two crystallographically independent mol-ecules. The pyrazole ring of one mol-ecule makes dihedral angles of 22.0 (3) and 3.5 (3)° with the pyrimidine and benzene rings, respectively; the corresponding values in the other mol-ecule are 9.2 (3) and 2.1 (3)°, respectively. The mol-ecules are linked by N-H⋯O, C-H⋯N and C-H⋯Br hydrogen bonds. ...[more]
