title: 1,3-Propanediammonium bis(3'-nitro-trans-cinnamate) and trans-1,2-cyclohexanediammonium bis(3'-nitro-trans-cinnamate).
abstract: In the title two adducts, C(3)H(12)N(2)(2+).2C(9)H(6)NO(4)(-), (I), and C(6)H(16)N(2)(2+).2C(9)H(6)NO(4)(-), (II), hydrogen bonds between the diammonium and carboxylate ions form a two-dimensional network parallel to the ab plane in (I) and one-dimensional chains along the c axis in (II). The cyclohexanediammonium ion in (II) has a crystallographic twofold axis.
