Structures of monoethanolamine (MEAM), diethanolamine (DEAM) and triethanolamine (TEAM)

“…25±27 The deviation of the nitrogen atom from the C3, C3', C3@ plane in compound 13 is 0.425(6) A Ê . It should be noted that the tricyclic system is not formed in the triethanolamine structure, 28,29 where intramolecular hydrogen bonds are absent. The crystal structure of 13 is stabilized by intermolecular hydrogen bonds of the OÐH ¼ O type.…”

“…6. The compound of triethanolamine and triethanolamine oxide (LUDDOD; Kemmitt et al, 2002) was not expected because the oxidation of the commonly used N(CH 2 CH 2 OH) 3 ligand was not anticipated and because in the structure of pure triethanolamine (BAFTAD10; Mootz et al, 1989) all hydroxyl groups act as both hydrogen-bond donors and acceptors. Furthermore, a structure of the pure oxidized molecule can be imagined in which there are columns of molecules in which the three hydroxyl groups of one molecule form hydrogen bonds to the NO group of the next (as they do in LUDDOD).…”

A list of 270 structures of ordered co-crystals of isomers, near isomers and molecules that are almost the same has been compiled. Searches for structures containing isomers could be automated by the use of IUPAC International Chemical Identifier (InChI™) strings but searches for co-crystals of very similar molecules were more labor intensive. Compounds in which the heteromolecular A···B interactions are clearly better than the average of the homomolecular A···A and B···B interactions were excluded. The two largest structural classes found include co-crystals of configurational diastereomers and of quasienantiomers (or quasiracemates). These two groups overlap. There are 114 co-crystals of diastereomers and the same number of quasiracemates, with 71 structures being counted in both groups; together the groups account for 157 structures or 58% of the total. The large number of quasiracemates is strong evidence for inversion symmetry being very favorable for crystal packing. Co-crystallization of two diastereomers is especially likely if a 1,1 switch of a methyl group and an H atom, or of an inversion of a [2.2.1] or [2.2.2] cage, in one of the diastereomers would make the two molecules enantiomers.
