Abstract
The compound (2-hydroxyethyl)piperazine-1,4-diium tetrachloroplombate(II) [C6H16N2O]PbCl4 was preparated at room temperature. Single crystal X-ray diffraction showed the formation of title compound consisting of polymeric 1-D endless inorganic chains. The different entities are held together via N-H···Cl, O-H···Cl and C-H···Cl hydrogen bonds to build a three dimensional network. This compound was also characterized by different techniques such as Powder X-Ray Diffraction, Infrared and Raman spectroscopy, UV absorption, Photoluminescence, XPS and DSC analysis.

A novel hybrid material, C6H16N2OPbCl4, has been successfully synthesized in nitrogen atmosphere by slow evaporation at room temperature. The compound structure was determined by single-crystal X–ray diffraction and crystallizes in the triclinic space group P-1 (a = 5.9926(2) Å, b = 10.3691(5) Å, c = 11.3558(4) Å, α = 111.755(4)°, β = 96.080(3)°, γ = 105.948(4)°, Z = 2) at 293 K. The structure is built up from anionic 1-D polymeric chains of PbCl4O octahedral extended along the (b + c)-axis. These chains are interconnected by OH⋯Cl hydrogen bonds to form inorganic layers parallel to (a, b + c) plane. The organic layers are inserted between the inorganic ones and connect them through NH⋯Cl and CH⋯Cl hydrogen bonds to build a three dimensional network. To gain more information about intermolecular interaction we used Hirshfeld surfaces associated with 2D finger plots. The optical and PL properties of the compound were investigated in the solid state at room temperature and exhibited two bands at 250 and 290 nm and a photoluminescence emission at 529 nm. Raman and infrared spectra were used to gain more information for vibrational modes of the title compound. As for thermal analysis, DSC analysis shows that this compound is stable at temperature below melting point. Finally, XPS analysis is achieved for analyzing the surface chemistry of C6H16N2OPbCl4 crystals.
