The asymmetric unit of the title compound, 2C(6)H(12)N(4)·C(8)H(12)O(4), contains one half-mol-ecule of e,e-trans-cyclo-hexane-1,4-dicarb-oxy-lic acid (the complete molecule being generated by inversion symmetry) and one mol-ecule of hexa-methyl-ene-tetra-mine (HMTA), which are connected by O-H⋯N hydrogen bonds. This forms isolated trimers that pack in a herringbone fashion.
