Synthesis, Crystal Structure, and Characterization of a New Organic-Inorganic Hybrid Material : H3AEP2·BiCl6·3Cl·2H2O

Abstract EN

The title compound is an organic-inorganic hybrid material.

The single crystal X-ray diffraction investigation reveals that the studied compound crystallizes in the orthorhombic system, space group Pbca with the following lattice parameters: a=12.108 (4) Å, b=19.403 (3) Å, c=24.933 (6) Å, and Z=8.

The crystal lattice is composed of a discrete (BiCl6)3- anion surrounded by piperazinium cations, chlorine anions, and water molecules.

Complex hydrogen bonding interactions between (BiCl6)3-, Cl−, organic cations, and water molecules form a three-dimensional network.

Room temperature IR, Raman spectroscopy, and optical absorption of the title compound were recorded and analysed.

The observed crystal morphology was compared to the simulated one using the Bravais-Friedel, Donnay-Harker model.
