K. Kocwin-Gielzak and B. Marciniak

Abstract: The crystal structure of the title compound, [Cu(C₂O₄)(C₆H₁₄N₂O)(H₂O)]·H₂O, includes a CuN₂O₃ coordination polyhedron in the shape of a slightly distorted square pyramid with bidentate morpholine and oxalate ligands. Copper(II) is coordinated by 4-(2-aminoethyl)morpholine (etMorph) N atoms, with Cu-N distances of 2.050 (3) and 1.985 (3) Å, and two carboxylate O atoms from the oxalate ligand, with Cu-O distances of 1.955 (2) and 1.965 (2) Å; both ligands are located in the basal plane, whereas a water molecule is apically positioned [Cu-O = 2.251 (3) Å]. The crystal packing is dominated by N-HO and O-HO hydrogen bonds.
