The crystal structure, including a graph-set analysis, of 1-[(2-hydroxy-2-methylpropyl)methylamino]-2-methylpropan-2-ol, C9H21NO2, is reported. The structure is characterized by unsymmetrical intra- and intermolecular O—H...O hydrogen bridges, giving rise to the formation of an infinite polymer consisting of eight-membered rings arranged in zigzag chains running along theaaxis.
The reaction of sodium chloride with 2-[bis(2-hydroxyethyl)amino]ethan-1-ol results in the formation of the title salt {[Na{N(CH2CH2OH)3}]Cl}
n
. The polymeric structure is characterized by a sodium cation coordinated by one nitrogen and five oxygen atoms in a distorted octahedral environment. The resulting one-dimensional {—O—Na—O—Na—O}— coordination polymer extends parallel to [010] and is connected through the chloride counter-anion via O—H...Cl hydrogen bonding, giving rise to a two-dimensional supramolecular structure parallel to (001).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
