Synthesis, crystal structure, vibrational and optical properties of chlorometalate hybrids incorporating (DABCOH(2))(2+) cations

摘要

Three organic-inorganic hybrid compounds based on chlorometalate anions and 1,4-Diazoniabicyclo[2.2.2loctane cations [(DABCOH(2))(2+)] have been synthesized by slow evaporation technique at ambient temperature. Their chemical formulas are (DABCOH(2))(2)[Sb2Cl10].2H(2)O (1), (DABCOH(2))(2)[Sb2C10]center dot H2O (2) and (DABCOH(2))(4)[Cd2Cl7,83] [Sb2Cl9,17]Cl center dot 4H(2)O (3). All compounds have been solved by single crystal X-ray diffraction method. The anionic layer of (1) consists of isolated [Sb2Cl10](4-) or bi-octahedra (OD). For the second compound (2), the anionic framework is formed by infinite zigzag chains of corner-sharing [SbC16)3- octahedra (1D). On the other hand, the crystal structure of (3) is built of [{(Cd2Cl7,83)(Sb2Cl9,17)(n)](7n-) polyanionic layers (2D). The vibrational properties of (1) and (2) have been studied via FT-IR spectroscopy with calculated semi empirical PM3 mode. The optical properties of (1) and (2) have been characterized, by means of UV-Visible Absorption, Photoluminescence spectroscopy and Time Resolved PL (TRPL), with structure to optical property correlations.
