Abstract
The complex, [Cu(dmap)(OAc)(H 2O)] 2· 2H 2O (dmap = N,N-dimethylaminopropanolato, OAc = acetato) was synthesized by drop-by-drop addition of N,N-dimethylaminopropanol to copper(II) acetate dihydrate suspended in toluene. The blue crystalline product was characterized by its melting point, elemental analysis, infrared spectral study, mass analysis, thermal analysis and by the single-crystal X-ray structure analysis. Compound ( 1) crystalizes in triclinic space group, P̄1, a= 6.3716(9) Å, b= 8.2719(12) Å, c= 10.9254(16) Å, α= 79.918(2)°, β= 81.812(2)°, γ= 77.171(2)° and Z= 1. The complex ( 1) is binuclear. The copper s’ environment is square pyramidal with chelating dimethylaminopropanol rings being in the equatorial and water molecules in axial positions. Acetate ligands are attached to Cu viaoxygen, in a monodentate mode while the C=O oxygen is involved in O···H–O H-bonds with water molecules. Dimethylaminopropanol serves as a chelating as well as bridging ligand.
