Abstract
Coordination compounds based on bis-quinolizidine alkaloids sparteine and & -isosparteine as ligands with Zn(II) and Cu(II) salts are described from the viewpoint of their spectroscopic and structural properties. In particular the complexes of LMX2 types where L = alkaloid, X = halides (Cl-, Br-, I-), pseudo-halides (CN-, SCN-) and oxy-anions (C4H5OO-, CH3COO-, NO3-).
Keywords: Alkaloids, sparteine, α-isosparteine, Zn(II) and Cu(II) complexes, X-ray structure, spectroscopic properties
