In this paper, with 2-oxo-propionic acid salicyloyl hydrazone as a ligand, one calcium complex, three copper complexes and thirteen rare earth(RE=La, Ce, Pr, Nd, Sm, Eu. Gd, Tb, Dy, Er, Tin, Yb and Lu) complexes have been synthesized. The crystals of four complexes were obtained, and the crystal structures were determined by single crystal X ray diffraction. One of the crystals is calcium complex, the other are binary and trinary complexes of copper.
