Abstract
Single crystals of [(CH3CH2)4N] Mn1,5 Cl3 4H2O Cl 2(H2O) were grown by the slow evaporation technique and characterized by means of single-crystal X-ray diffraction, FT-IR and Raman spectroscopy. The title compound belongs to the triclinic space group P with the following unit cell dimensions: a =7.5425(4) Å, b=9.8464 Å, c=13.7671(6) Å, α=89.951(3)°,β=89.753(3)°, γ=81.861(3)°, Z=4. These structures have solved using direct methods and refined by least-squares analysis. The structure was solved by the direct method and refined to final R value of 0.0567. The projection of [(CH3CH2)4N] Mn1,5 Cl3 4H2O Cl 2(H2O) in the plan (a,b) shows an arrangement in layers perpendicular to the direction b . The structure consists of infinite parallel two-dimensional planes built connected ions and water molecules by strong O-H…O and O-H…Cl hydrogen bonding.
Highlights
The combination of organic molecules and inorganic materials was the starting point for the development of new hybrid compounds, with expected physical and chemical properties. These compounds have attracted great attention because of their unique opportunity to combine the remarkable features of organic compounds with those of inorganic materials
The Fourier transform infrared (FT-IR) spectrum of the title compound was recorded in the range 4000-400 cm-1, with samples in KBr pellets using PERKIN-ELMER FT-IR spectrometer
The asymmetric unit (Fig. 1) consists of a single Mn(1) Cl 2H2O moiety, Mn(2) Cl2 2H2O moiety, two water molecules 2H2O, a chloride anion Cl and tetraethylammonium [(C2H5)4N] cation, which under the appropriate symmetry operations yields a molecular structure as shown in figure 2
Summary
The combination of organic molecules and inorganic materials was the starting point for the development of new hybrid compounds, with expected physical and chemical properties. These compounds have attracted great attention because of their unique opportunity to combine the remarkable features of organic compounds with those of inorganic materials. Their applications have been explored and reported in various fields, such as magnetism, conductive, luminescence and optics [1,2,3,4,5]. The present work deals with the growth, single X-ray diffraction (XRD) study and the detailed vibrational spectral analysis of a new organic-inorganic crystal: [(CH3 CH2)4N] Mn1,5 Cl3 4H2O Cl 2(H2O)
