Synthesis, crystal structure and spectroscopic studies of a supramolecular compound [Cu(IDA)(phen)(H2O)] • 4H2O built from π-π interactions and hydrogen bonds

The stoichiometric reaction of (MeCOO)(2)Cu, iminodiacetic acid (H(2)IDA) and 1,10-phenanthroline (phen) in H2O yields the novel complex [Cu(IDA)(phen)(H2O)].4H(2)O (1). An X-ray structural determination shows that the dimer was formed by diverse hydrogen bonding and pi-pi interactions, and that each metal Cu-II center is six-coordinate, exhibiting an octahedral coordination. The complex was also characterized by t.g.a., FT-IR and u.v.-vis. spectroscopy and the electrochemical behavior of (1) was also studied. Its electronic spectra have been calculated by the CIS method.
