Abstract
The crystal structure of a 6-amino hexanoic acid-vermiculite complex has been determined using X-ray single crystal diffraction method.
The complex has a long spacing of 17.32 ± 0.04 Å and the monoclinic unit cell a = 5.33 ± 0.01, b = 9.18 ± 0.02, c = 17.45 ± 0.04 Å, β = 97°, Z = 2. The probable space group is C2.
Electron density projections on (100) and (010) planes show that the organic molecules form two layers with long chains parallel to the b-axis. The plane of the zig-zag hydrocarbon chain is tilted at 50° from the (001) plane. Therefore the complex belongs to the α-configuration. Disorder and hydrogen bonding are discussed.
