4-Nitro­phenol–piperazine (2/1)

In the title adduct, C(6)H(5)NO(3)·0.5C(4)H(10)N(2), the piperazine ring possesses inversion symmetry and has a chair conformation. Its mean plane makes a dihedral angle of 65.45 (7)° with the 4-nitro­phenol ring. In the crystal, the piperazine ring is linked to two 4-nitro­phenol mol­ecules via O—H...

Sumario:In the title adduct, C(6)H(5)NO(3)·0.5C(4)H(10)N(2), the piperazine ring possesses inversion symmetry and has a chair conformation. Its mean plane makes a dihedral angle of 65.45 (7)° with the 4-nitro­phenol ring. In the crystal, the piperazine ring is linked to two 4-nitro­phenol mol­ecules via O—H⋯N hydrogen bonds. The mol­ecules are also linked via bifurcated N—H⋯(O,O) hydrogen bonds involving the NO(2) O atoms, forming a two-dimensional network lying parallel to (102). The networks are linked via C—H⋯O hydrogen bonds, forming a three-dimensional structure.
