Synthesis, Hirshfeld surface analysis and physicochemical studies of non-centrosymmetric semi-organic compound: [C10H15N2](H2PO4)

Abstract

Abstract Organic–inorganic hybrid material, [C10H15N2](H2PO4), was synthesized and characterized by physicochemical studies such as FT-IR, NMR, UV–Visible spectroscopy, thermal analysis and electrical conductivity. The FT-IR spectrum of the polycrystalline sample shows the functional groups of organic cation and [H2PO4]− anion. TGA and DSC analysis were carried out to study the thermal behavior of the prepared material. Solid-state 13C and 31P MAS NMR spectroscopy are in agreement with the X-ray structure. The presence of wide transparency window in UV–Visible region makes that [C10H15N2](H2PO4) is suitable for opto-electronic device applications. The Hirshfeld surface analysis was conducted to investigate intermolecular interactions and associated with 2D fingerprint plots revealing the relative contributions of these interactions in the crystal structure quantitatively. The electrical conductivity measurements shows that the [C10H15N2](H2PO4) has a conductivity value which goes from 2.22 × 10−6Ω−1cm−1 at room temperature (298 K) to 1.93 × 10−5Ω−1cm−1 at 393 K.
