| Di-bis Pentahydrate von fünf Alkylendiaminen. Eine Fallstudie zu ein-und zweidimensionalen Wasserpolymeren in Festkörpern [1]-to Pentahydrates of Five Alkylenediamines. A Case Study of One-and Two-Dimensional Water Polymers in Solids [1]  | | | | Abstract
| The crystal structures of five low-melting hydrates of »-alkane-a,u;-diamines, H2N(CH2)"NH2 • x H20 , for short C" ■ x W, have been determined. As a common feature, the water molecules are mutually linked by hydrogen bonds O-H -O to form low-dimensional polymers. These are a meandering chain in C2 • 2 W (space group I 2la, Z -4 formula units per unit cell), a zig zag chain in C6 • 2 W (P 2,/c, Z = 2), a ribbon of consecutively condensed five-membered rings in C3 • 3 W (P 2,/c, Z = 4) and a layer of condensed and spiro-linked rings of varying size each in C7 • 3 W (P i, Z = 4) and C4 • 5 W (C 21c, Z = 4). Further hydrogen bonding, between the water polymers and the bifunctional amine molecules, leads to overall connectivities which are three-dimensional in each structure. | | | |
