© 2020 Elsevier B.V. The interaction of Cu(NO3)2 with pentyl {[benzyl(dibutyl)ammonio]methyl}phosphonate (L) was studied by Fourier Transform Infrared (FTIR) spectroscopy with the use of isomolar series solution. The changes in the nitro group stretching bands and phosphoryl P[dbnd]O stretching bands of L were monitored. The copper(II) complex of pentyl {[benzyl(dibutyl)ammonio]methyl}phosphonate, has been synthesized and characterized by routine X-ray, IR and NMR 1H, 31P and 13C spectroscopy. Single crystal X-ray diffraction analysis showed that crystal is formed by the dinuclear centrosymmetric metal complex, which is formed by copper, pentyl {[benzyl(dibutyl)ammonio]methyl}phosphonate and NO3− groups in a 2:2:4 ratio.
