| Tautomere Wasserschichten. Bildung und Struktur tiefschmelzender Trihydrate von Triethylamin und 4-Methylpyridin [1] Tautomeric Water Layers. Formation and Structure of Low-Melting Trihydrates of Triethylamine and 4-Methylpyridine [1]  | | | | Abstract
| Low-melting trihydrates of triethylamine (E t3N) and 4-methylpyridine (4-M ePy) have been confirmed and detected by phase analysis and the crystal structures determined. Both are monoclinic with space group P 2!/c and Z = 4 formula units per unit cell. The lattice parameters are a = 13.606, b = 6.291, c = 12.412 A , and ß = 99.47° at -1 0 0 °C for Et3N -3 H 20 , and a = 9.982, b = 6.877, c = 12.958 Ä , and ß = 103.50° at -9 0 °C for 4-M eP y-3 H20 . The water m olecules in the two structures are hydrogen-bonded in condensed four-, five-, and six-membered rings with 1:2:1 ratio, thus forming characteristic layers parallel (1 0 0) of identical topology and tautomeric to each other. The amine m olecules are linked to both sides of the layers by O -H — N bonds from different O atoms. | | | |
