Synthesis, spectral and structural characterization of zinc(II) methacrylate complexes with sparteine and α-isosparteine: The role of hydrogen bonds and dipolar interactions in stabilizing the molecular structure

New complexes of zinc(II) methacrylate of the general formula [C15H26N2Zn(C4H5O2)2] where [C15H26N2] is a sparteine or α-isosparteine have been obtained by direct synthesis using zinc salt and an appropriate alkaloid. The compounds have been characterized by elemental analysis, mass spectrometry, IR and NMR spectroscopy as well as by X-ray methods.
