Space group revsion of the triclinic polymorph of salicylaldehyde azine

Space group revsion of the triclinic polymorph of salicylaldehyde 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-1 with Z = 4 [El-Medani, Aboaly, Abdalla & Ramadan (2004). Spectrosc. Lett. 37, 619&#...
