One-dimensional array of acetylene molecules adsorbed in a metal-organic microporous material

  • Only SPring-8

Body text

Powder diffraction is a powerful technique to study crystal structures. Using this technique, one can measure structural parameters such as lattice parameters, atomic positions, etc of crystalline materials. By using synchrotron radiation one can also obtain charge density level structures closely related with physical properties as well as structural parameters. The figure shows charge density distributions obtained by analyzing diffraction data of a metal-organic solid under acetylene gas adsorption. These data reveal the fact that adsorbed acetylene molecules(green color)form a one-dimensional array in a metal-organic microporous material.
