Two new mono- and dinuclear Cu(II) complexes,
namely [CuL1]0.5H2O (1) and [(Cu2(L2)2)(DMF)]
0.5DMF (2) (H2L1 = 1,2-bis{[(Z)-(3-methyl-5-oxo-1-phenyl-
1H-pyrazolidin-4(4H)-yl)(phenyl)]methylene-aminooxy}
ethane; H2L2 = 1,3-bis{[(Z)-(3-methyl-5-oxo-1-phenyl-1Hpyrazolidin-
4(4H)-yl)(phenyl)] methyleneaminooxy}propane),
have been synthesized and characterized by X-ray
crystallography.
