Isoguaninium chloride structure

The structure of the isoguaninium chloride displays two kinds of mol­ecular tapes parallel to (010) and (50\overline{4}). The tapes are formed by dimers of isoguaninium cations inter­acting with chloride anions.

Z/E-Isomerism of 3-[4-(di­methyl­amino)­phen­yl]-2-(2,4,6-tri­bromo­phen­yl)acrylo­nitrile: crystal structures and secondary inter­molecular inter­actions

The crystal structures of the energetically similar Z and E isomers of 3-[4-(di­methyl­amino)­phen­yl]-2-(2,4,6-tri­bromo­phen­yl)acrylo­nitrile differ in the nature of their strong inter­molecular nonbonding inter­actions, which are Br⋯N in the case of the Z isomer and Br⋯Br for the E isomer.

Temperature-induced polymorphism of salt cocrystal solvates of a pyridyl bis-urea macrocycle and naphthalene-1,5-di­sulfonic acid

Mol­ecular salts were formed by proton transfer from naphthalene-1,5-di­sulfonic acid to a pyridyl bis-urea macrocycle. Two DMSO-solvated salts displaying two distinct conformations of the macrocycle were obtained upon slow cooling of DMSO–aceto­nitrile solutions from two temperatures (363 and 393 K).
