Synthesis and structural studies of some metal(II) complexes of 5-methyloxazolidine-4-carboxylic acid
摘要:
The reactions of formaldehyde with the metal(II) chelates of L-threonine (metal = copper, nickel, cobalt and zinc) result in the formation of the metal(II) complexes of 5-methyloxazolidine-4-carboxylic acid. The copper(II) complex, C10H20N2O8Cu, is obtained from the recrystallization of its 3-hydroxymethyl derivative, C12H24N2O10Cu, which initially forms. C10H20N2O8Cu crystallizes in the orthorhombic space group P2(1)2(1)2(1) with a = 8.166(1), b = 8.936(1), c = 20.463(5) angstrom and Z = 4. The structure has been refined to R = 0.021 and R(w) = 0.021 based on 1444 reflections with l > 2.5-sigma-(l). The geometry about copper is based on a square pyramid with a coordinated water in the apical position. The synthesized compounds are characterized by microanalysis, magnetic and thermal data as well as examinations of their electronic and infrared spectra.
