| Abstract: | The complex [Cu (phen)2(POAc)3 ]ClO4·4h2O has been synthesized and investigated by elemental analysis, IR spectroscopy and X‐ray diffraction methods, where phen = 1,10‐phenanthroline, POAc? = phenylacetate group). The complex crystallizes in the triclinic space group Pi with two molecules in a unit cell of dimensions a = 1.0579(2) nm, b = 1.2423(3) nm, c = 1.9190(4) nm, a = 71.84(1)°, β = 80.50(2)°, Y = 88.60(1)°, V = 2.3625(9) nm3, R =0.0407 and Rw = 0.0656. The complex results from bridging of two Cu (phen)2+ units by three carboxylate groups, and each Cu2+ ion is in a distorted square pyramidal geometry with two nitrogen atoms of phen and three carboxylate oxygen atoms of POAc?. It has been showed that intramolecular stacking interactions occur between the phenyl moieties of POAc? and aromatic rings of phen, leading to a novel molecule structure with two coordinating modes of carboxylate ligands, of which two phenylacetates are μ2—carboxylate—O‐bridging ligands, and the other is a μ2—carboxylate—O,O′‐bridging ligand. |
