Abstract

The reaction of trimesic acid (H3TMA) with 2,6-bis(4-pyridylmethylene)cyclohexanone (1) in MeOH and phenol resulted in a co-crystal H3TMA·1 (1 : 1). The crystal structure of this co-crystal was found to contain a triply interpenetrated (6,3) hydrogen bonded network. The repeat of this reaction without PhOH resulted in crystals of an ionic compound which also contains both the components in 1 : 1 ratio. The crystal structure of this ionic solid exhibits a doubly interpenetrated three-dimensional hydrogen bonded network.
