Abstract
(Pyrazol-1-yl)acetic acid (HL1, 1) and (pyridin-2-yl)acetic acid have been successfully condensed with the terminal amino group of a Phe−Gly dipeptide to generate the derivatives PzCH2–Phe−Gly (H3L2, 7) and PyCH2–Phe−Gly (H3L3, 8) respectively, which contain ATCUN-like metal ion binding sites. The crystal structures of 1 and the copper(II) complexes Cu(L1)2(H2O)2 (2) and [nBu4N][Cu(L2)] (9) are described. Complex 2 has a tetragonally-elongated, Jahn–Teller distorted octahedral geometry and complex 9 is square-planar. The structural similarity of the copper(II) complexes of 7 and 8 is demonstrated by their almost identical electronic absorption and EPR spectra. (© Wiley-VCH Verlag GmbH & Co.
