Abstract
There are two independent but virtually identical mol-ecules of each component in the asymmetric unit of the title 1:1 adduct, C(6)H(12)N(2)·C(6)H(6)O(2). In the crystal, the constituents are connected into a supra-molecular chain along the b axis by O-H⋯N hydrogen bonds. Weak C-H⋯O bonds cross-link the chains.
