Abstract

Chemical and spectroscopic (UV; 1H, 13C, 15N NMR; HRMS) studies determined the structure of 1,1,4,10,10-pentaamino-2,3,5,6,8,9-hexaazadeca-1,3,5,7,9-pentaene for the red-violet compound, which was obtained by treating aminoguanidine hydrochloride with KOH. X-ray powder diffraction and lattice-constrained PBC-DFT optimization confirmed this structure and defined a linear all-trans configuration.
