Dibromidobis­(4-hydr­oxy-1,5-dimethyl-2-phenyl-3-pyrazolone)zinc(II)

In the title compound, [ZnBr(2)(C(11)H(12)N(2)O(2))(2)], the Zn(II) ion is coordinated by two Br atoms and two O atoms from two 4-hydroxy­anti­pyrine mol­ecules via the carbonyl O atoms, which act as monodentate ligands, giving rise to a distorted tetra­hedral geometry. The values of the bond angles...

description In the title compound, [ZnBr(2)(C(11)H(12)N(2)O(2))(2)], the Zn(II) ion is coordinated by two Br atoms and two O atoms from two 4-hydroxy­anti­pyrine mol­ecules via the carbonyl O atoms, which act as monodentate ligands, giving rise to a distorted tetra­hedral geometry. The values of the bond angles at the Zn atom are in the range 99.4 (1) to 113.2 (1)°. The presence of O—H⋯O and O—H⋯Br intra­molecular hydrogen bonds can explain the difference between the two Zn—O [1.961 (3)/2.015 (3) Å] and the two Zn—Br [2.350 (1)/2.378 (1) Å] bond lengths. The crystal structure is governed by C—H⋯O, C—H⋯Br and Zn—Br⋯Cg(π-ring) inter­actions.
