Crystal structure of the bis(cyclohexylammonium) succinate succinic acid salt adduct

The crystal structure of the title salt adduct, 2C(6)H(14)N(+)center dot C4H4O42-center dot C4H6O4, consists of two cyclohexylammonium cations, one succcinate dianion and one neutral succinic acid molecule. Succinate dianions and succinic acid molecules are self-assembled head-to-tail through O-H center dot center dot center dot O hydrogen bonds and adopt a syn-syn configuration, leading to a strand-like arrangement along [101]. The cyclohexylammonium cations have a chair conformation and act as multidentate hydrogen-bond donors linking adjacent strands through intermolecular NH center dot center dot center dot O interactions to both the succinate and the succinic acid components. This results in two-dimensional supramolecular layered structures lying parallel to (010).
