Crystal structure determination and vibrational spectroscopic studies of terephthalate and 2-amino terephthalate complexes with the 1,10-di-amonium-decane cation

Abstract

Abstract Recent advances in crystal engineering have shown an increasing trend in the promising employment of co-crystals obtained by benzene poly-carboxylic acids and polyamines. In this work, we present the synthesis and characterization of two “new” complexes coming from terephthalic derivates and a long chain diamine (1,10-diaminodecane). We firstly report the X-ray single crystal diffraction analysis and FT-IR results on two of these complexes. We then assign the observed experimental vibrational modes by the support of DFT analysis.
