font size="2"> We examine the role of the lattice symmetry in the electronic paths for superexchange interactions in copper-amino acid complexes. For this purpose we obtained by ESR spectroscopy the exchange-coupling parameters spectroscopy the exchange-coupling parameters J between coppers in rruns-bis(~-2-aminobutyrato)coppe.r(ll), Cu(L-but),, and in rrunr-bis(~,~-2-aminobutyrato)cop~er(IIC),u (D,L-but)> Also, we solved the structure of C~(L-but)C~U, (CO,CH(NH~)CH~CHa~nd) ~co, mpared
