The asymmetric unit of the title co-crystal, 2C(13)H(10)N(2)O(3)·C(14)H(14)N(4)O(2), comprises one mol-ecule of 2-(4-hydroxy-phenyl-diazen-yl)benzoic acid and half of an N,N'-bis-(4-pyridylmeth-yl)oxamide mol-ecule as the latter is disposed about an inversion centre. The most notable feature of the crystal structure is the formation of supra-molecular chains arising from hydr-oxy-pyridine O-H⋯N contacts and amide-hydr-oxy C-H⋯O contacts. These give rise to 40-membered {⋯OH⋯NNC(4)OH⋯NC(4)NC(2)NH} ...[more]
