Journal of Coordination Chemistry, 62(20), 3250-3258.0095-8972https://doi.org/10.1080/00958970903051924https://www.tandfonline.com/doi/full/10.1080/00958970903051924http://hdl.handle.net/11452/23084Three new complexes, [Cu(barb)2(aepip)] center dot 0.5H2O (1), [Cu(barb)2(aepyrd)] (2), and [Cu(barb)2(aemrph)] (3), have been synthesized by reaction of 5,5-diethlybarbiturate anion (barb) with copper(II) in the presence of (2-aminoethyl)piperidine (aepip), -pyrrolidine (aepyrd), and -morpholine (aemrph). All complexes were characterized by elemental analysis, spectroscopic (IR and UV/Vis), thermal (DTA-TGA), and magnetic susceptibility measurements. X-ray single crystal diffraction shows that 1 and 2 are discrete mononuclear species, in which copper(II) is coordinated by two bidentate barb ligands and a chelating aepip or aepyrd, forming a square-pyramidal coordination geometry. Complexes 1 and 2 show unequal coordination of barb, one N-coordinate, and one bidentate. Complex 3 is also mononuclear, but copper(II) is square-planar with two N-coordinated barb and one bidentate aemorph. Molecules of 1-3 are bridged by strong hydrogen bonds to generate 1-D or 2-D supramolecular networks. Spectral and thermal data for 1-3 are in agreement with crystal structures.eninfo:eu-repo/semantics/closedAccess(2-Aminoethyl)morpholine(2-Aminoethyl)piperidine(2-Aminoethyl)pyrrolidine5,5-DiethylbarbiturateCopper(II)Molecular-structureLigandsChemistryArticle0002695419000022-s2.0-69949108520325032586220Chemistry, inorganic & nuclearThiobarbituric Acid; Barbiturates; DMV
