cis-Cyclo­hexane-1,3-di­carb­oxy­lic acid–N,N′-(pen­tane-1,5-di­yl)bis­(pyridine-4-carboxamide)–water (1/1/2)

The title cocrystal, C8H12O4·C17H20N4O2·2H2O, shows O—H⋯N hydrogen bonded supra­molecular chain motifs of cis-1,3-cyclo­hexa­nedi­carb­oxy­lic acid (H2cdc) mol­ecules alternating with N,N′-(pentane-1,5-di­yl)bis­(pyridine-4-carboxamide)­pentane (bpcpe) mol­ecules. These chain motifs are aggregated by C—H⋯O inter­actions into supra­molecular layers and slabs, which are stacked into the three-dimensional crystal structure by means of O—H⋯O inter­actions mediated by the water mol­ecules of crystallization.
