Abstract
The syntheses of the racemic amino alcohol rac-N(CH2CMe2OH)(CMe2CH2OH)(CH2CHMeOH) (L22'1*H3, 2) and its representative N(CH2CMe2OH)(CMe2CH2OH)(CH2C(R)HMeOH) (L22'1RH3, 3) with the stereogenic carbon center being R-configured are reported. Also reported are the stannatranes L22'1*SnOt-Bu (4) L22'1RSnOt-Bu (6) and germatranes L22'1*GeOEt (5) and L22'1RGeOEt (7) as well as the trinuclear tin oxocluster [(μ3-O)(μ3-O-t-Bu){SnL22'1R}3] (8). NMR and IR spectroscopy, electrospray ionization mass spectrometry (ESI MS), and single crystal X-ray diffraction analysis characterize these compounds. Computational studies accompany the experimental work and help understand the diastereoselectivity observed in the course of the metallatrane syntheses.

Abstract
The synthetic protocols, structural aspects, and spectroscopic aspects of mononuclear pseudostannatranes possessing a [4.4.3.01,5]tridecane cage have been reported. A tripodal ligand N(CH2CH2OH){CH2(2-t-Bu-4-Me-C6H2OH)}2 (H3L) having unsymmetrical arms was reacted with n-butyltrichlorostannane, phenyltrichlorostannane, and tin tetrachloride under different solvent systems to obtain pseudostannatranes (1-3). The reaction of n-butyltrichlorostannane and the ligand in CH3OH/Na/THF yielded an aqua complex of pseudostannatrane [LSnBu(H2O)] (1a), which was crystallized as its acetone solvate (i.e 1a·Me2CO). However, the same reactants yielded methanol complex [LSnBu(CH3OH)] (1b) when the reaction was carried out in the NaOCH3/C2H5OH system. Similarly, the reaction of phenyltrichlorostannane and the ligand under these solvent systems yielded pseudostannatranes, i.e., an aqua complex [LSnPh(H2O)] (2a) and a methanol complex [LSnPh(CH3OH)] (2b) (where 2a was crystallized as 2a·Me2CO). The reaction of tin tetrachloride and the ligand in the Et3N/THF system resulted in the formation of pseudostannatrane [LHSnCl2] (3). A similar product was isolated as its triethylamine solvate (3·NEt3) due to the disproportion reaction when PhSnCl3 was reacted with the ligand in the Et3N/C6H5CH3 system, which demonstrates the first report on the reverse Kocheshkov reaction in pseudostannatranes. The experimental findings on the formation of 3·NEt3 due to the reverse Kocheshkov reaction have been corroborated with 119Sn NMR spectroscopy and density functional calculations that provide insightful information about the underlying details of the reaction route.

Abstract
The syntheses of the novel stannatranes N(CH2CMe2O)3Sn-(1 S)-(-)-OC(O)C(OMe)(CF3)(C6H5), 1( S, Δ), and N(CH2CMe2O)3Sn-(1 R)-(+)-OC(O)C(OMe)(CF3)(C6H5), 2( R, Λ), and germatranes N(CH2CMe2O)3Ge-(1 S)-(-)-OC(O)C(OMe)(CF3)(C6H5), 3( S, Δ), and N(CH2CMe2O)3Ge-(1 R)-(+)-OC(O)C(OMe)(CF3)(C6H5), 4( R, Λ) (with 1, S, Δ-configured/2, R, Λ-configured and 3, S, Δ-configured/4, R, Λ-configured being pairs of enantiomers) are reported. The compounds were characterized by NMR and IR spectroscopy, electrospray ionization mass spectrometry, and single crystal X-ray diffraction analysis. The epimerization via Λ ⇌ Δ ring flip of the enantiomeric stannatrane pair 1( S, Δ)/2( R, Λ) was investigated by NMR experiments at variable temperatures and density functional theory (DFT) calculations.

Abstract
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).
