The amino alcohol MeN(CH2CMe2OH)2

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 the a axis

The sodium chloride complex catena-poly[[{μ3-2-[bis(2-hydroxyethyl)amino]ethan-1-ol}sodium] chloride], N(CH2CH2OH)3·NaCl

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)

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)

Simplicity Meets Beauty. Trapping Molecular Dimethyltin Oxide in the Novel Organotinoxo Cluster [MeN(CH₂CH₂O)₂SnMe₂·Me₂SnO]₃

The syntheses are reported of the 1,1,5-trimethyl-2,8-dioxa-5-aza-1-stannabicyclo[3.3.0]­octane MeN­(CH₂CH₂O)₂SnMe₂ (<b>1</b>), its monosodium aminoalcoholate adduct [MeN­(CH₂CH₂O)₂SnMe₂·MeN­(CH₂CH₂ONa)­(CH₂CH₂OH)]₂ (<b>2</b>), and the hexanuclear organotin oxo cluster [MeN­(CH₂CH₂O)₂SnMe₂·Me₂SnO]₃ (<b>3</b>). The compounds were characterized by ¹H, ¹³C, and ¹¹⁹Sn NMR spectroscopy, electrospray ionization mass spectrometry, and single-crystal X-ray diffraction analysis. In the solid state, compound <b>1</b> is a tetramer that is brought about by intermolecular O→Sn interactions. In solution, however, it shows a monomer ⇌ dimer equilibrium that is fast on the ¹H, ¹³C, and ¹¹⁹Sn NMR time scales at room temperature. All compounds show intramolecular N→Sn interactions at Sn–N distances ranging between 2.378(3) Å (<b>2</b>) and 3.026(3) Å (<b>3</b>·0.25H₂O). Compound <b>3</b> can formally be regarded as a molecular dimethyltin oxide being trapped by head-to-tail complexation with a stannabicyclooctane. In solution, it slowly falls apart into <b>1</b> and Me₂SnO
