Space group revsion of the triclinic polymorph of salicyl­aldehyde azine

The structure of the title compound, C(14)H(12)N(2)O(2) {systematic name: 2,2′-[hydrazinediylidenebis(methanylyl­idene)]diphen­ol}, has already been determined in the triclinic space group P [Image: see text] with Z = 4 [El-Medani, Aboaly, Abdalla & Ramadan (2004 ▶). Spectrosc. Lett. 37, 619–632...

description The structure of the title compound, C(14)H(12)N(2)O(2) {systematic name: 2,2′-[hydrazinediylidenebis(methanylyl­idene)]diphen­ol}, has already been determined in the triclinic space group P [Image: see text] with Z = 4 [El-Medani, Aboaly, Abdalla & Ramadan (2004 ▶). Spectrosc. Lett. 37, 619–632]. However, the correct space group should be P2(1)/c with Z = 4. This structure is a new polymorph of the already known monoclinic polymorph of salicyladehyde azine, which crystallizes in space group P2(1)/n with Z = 2. The benzene rings form a dihedral angle of 46.12 (9)°. Two intramolucular O—H⋯N hydrogen bonds occur.
