%X 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: £¿(4) £¿, £¿(3) £¿, £¿(6) £¿, and . The crystal lattice is composed of a discrete anion surrounded by piperazinium cations, chlorine anions, and water molecules. Complex hydrogen bonding interactions between , , 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. 1. Introduction Investigations of compounds, possessing organic cations and inorganic anions, evoke interesting properties because they provide original supramolecular networks. Heterocyclic cations and halobismuthates (III) strictly connected with the arrangement of hydrogen bond system generate interesting supramolecular assemblies [1]. The size of the organic cations, their symmetry, and ability to form the hydrogen bonds determine the physical properties in these materials (e.g., nonlinear optical properties, luminescence, conductivity etc.) [2¨C6]. The halobismuthate (III) family, in particular the chlorobismuthate, is composed of distorted isolated octahedra or connected by corners, edges, or faces forming ribbons, plans, or layers. The cavities between inorganic moieties are filled by organic cations to anionic framework through hydrogen bonds and/or electrostatic interactions. To advance our understanding of the principals governing the structural properties, especially the role played by hydrogen bonds, we have replaced the alkyl ammonium cations used so far [7, 8] with those containing more nitrogen atoms in their asymmetric unit. In this case, we used the 1-(2-aminoethyl) piperazine (AEP), an electron donor, which is a derivative of piperazine and contains primary, secondary, and tertiary nitrogen atoms. We synthesized a new zero-dimensional organic-inorganic material . In this paper, we report the single crystal X-ray diffraction study, infrared spectroscopy (IR), Raman spectroscopy, and optical absorption measurements. The crystal shape morphology calculation using the Bravais-Friedel, Donnay-Harker (BFDH) model is also reported. 2. Experimental Details 2.1.
