Synthesis, Crystal Structure, and Characterization of Ternary Copper(II) Complex Derived from N-(salicylidene)-L-valine

[摘要] Ternary Schiff base copper(II) complex [CuL(tmpda)] (where H2L is N-(salicylidene)-L-valine; tmpda is N,N,N?,N?-tetramethyl-1,3-propanediamine) has been characterized by UV-Vis., FTIR, and single crystal XRD. The crystal structure displays a distorted square pyramidal geometry in which Schiff base is bonded to the Cu(II) ion via phenolate oxygen, imine nitrogen, and an oxygen atom of the carboxylate group through the basal plane and the chelating diamine, N,N,N?,N?-tetramethyl-1,3-propanediamine, displays an axial and equatorial mode of binding via NN-donor atoms.
