چکیده
The title compound, [Cu(C(2)O(4))(2)(C(6)H(14)NO)(2)], was synthesized by mixing diacetonamine hydrogen oxalate and copper sulfate in ethanol/water. The mol-ecule is centrosymmetric, so two pairs of equivalent ligands lie trans to each other. The Cu(II) center, located on a position with 2/m site symmetry, is six-coordinated by four O atoms from two oxalate ligands at short distances and the carbonyl O atoms from the 4-amino-4-methyl-pentan-2-one ligands at longer distances. Mol-ecules are linked through inter-molecular N-H⋯O hydrogen bonds between the amino groups and carbonyl O atoms; no intra-molecular hydrogen bonds are formed.

A discrete neutral Cu(II) complex, [Cu(CF(3)SO(3))(2)(C(16)H(18)N(4))], has been derived from the symmetrical tetra-dentate Schiff base, N,N'-bis-[1-(pyridin-2-yl)ethyl-idene]ethane-1,2-diamine. The copper centre assumes a tetra-gonally distorted pseudo-octa-hedral geometry with the O atoms of two trifluoro-methane-sulfonate anions coordinated weakly in the axial positions. The Cu-N distances l...
