Abstract
(2,4,6-Trinitrophenyl)guanidine (picrylguanidine), C7H6N6O6, from the reaction of picrylsulfonic acid with guanidine carbonate, forms a three-dimensional framewok structure through extensive hydrogen-bonding interactions, extending the centrosymmetric cyclic R2/2(6) dimer association which includes duplex R2/2(8) guanidine N-H...O interactions. The guanidine substituent chain has an endo [Ph-N=C(NH2)2] bond sequence rather than the less sterically encumbered exo [Ph-NH-C=NH(NH2)] sequence of the tautomeric form. As a result, there is significant bond-angle distortion about the C(-N=) of the aromatic ring.

Citation countsare sourced monthly from Scopus and Web of Science citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science generally from 1980 onwards.
