Complexes of copper(II) carboxylates with 2-aminoethanol - syntheses, characterization and fungicidal activity; crystal structure of Cu(O2CC8H17)2(NH2C2H4OH)2
摘要:
Complexes of copper(II) octanoate, nonanoate and decanoate with 2-aminoethanol (ethanolamine) have been synthesized and characterized. The crystal structure of Cu(O2CC8H17)(2)(NH2C2H4OH)(2) consists of mononuclear units with pairs of amino nitrogen atoms and deprotonated nonanoato oxygen atoms forming a square coordination plane around the central copper. The hydroxyl oxygen atoms from the 2-aminoethanol ligands are positioned axially with respect to the coordination plane. Results of screening for fungicidal activity against the wood-rotting fungus Trametes versicolor (L. ex Fr.) Pilat show that the complexes totally inhibit fungal growth at a concentration of 1.0 x 10(-3) mol/l but only partially at a concentration of 5.0 x 10 mol/l. (C) 1997 Elsevier Science Ltd.
