title: Crystal structure of the bis-(cyclo-hexyl-ammonium) succinate succinic acid salt adduct.
abstract: The crystal structure of the title salt adduct, 2C6H14N(+)·C4H4O4 (2-)·C4H6O4, consists of two cyclo-hexyl-ammonium cations, one succcinate dianion and one neutral succinic acid mol-ecule. Succinate dianions and succinic acid mol-ecules are self-assembled head-to-tail through O-H⋯O hydrogen bonds and adopt a syn-syn configuration, leading to a strand-like arrangement along [101]. The cyclo-hexyl-ammonium cations have a chair conformation and act as multidentate hydrogen-bond donors linking adjacent strands through inter-molecular N-H⋯O inter-actions to both the succinate and the succinic acid components. This results in two-dimensional supra-molecular layered structures lying parallel to (010).
