Space group revsion of the triclinic polymorph of salicyl-aldehyde azine
The structure of the title compound, C14H12N2O2 {systematic name: 2,2′-[hydrazinediylidenebis(methanylylidene)]diphenol}, has already been determined in the triclinic space group P An external file that holds a picture, illustration, etc. Object name is e-68-0o255-efi1.jpg with Z = 4 [El-Medani, Aboaly, Abdalla & Ramadan (2004 [triangle]). Spectrosc. Lett. 37, 619–632]. However, the correct space group should be P21/c with Z = 4. This structure is a new polymorph of the already known monoclinic polymorph of salicyladehyde azine, which crystallizes in space group P21/n with Z = 2. The benzene rings form a dihedral angle of 46.12 (9)°. Two intramolucular O—H[cdots, three dots, centered]N hydrogen bonds occur.Download full text files
