title: Structural and spectroscopic characterization of aqua-diargininate-copper(II)-carbonate monohydrate.
abstract: The molecular structure of the title complex, [Cu(C6H14N4O2)2(H2O)]CO3.H(2)O, was determined by single crystal X-ray diffractometry. It crystallizes in the monoclinic space group P2(1), with Z = 2. The Cu(II) ion is in a square pyramidal environment, trans coordinated at the basis by two argininate groups acting as bidentate ligands through their amino nitrogen and carboxylate oxygen atoms. The coordination around copper is completed by a water molecule at the pyramid apex. The infrared, Raman and electronic spectra are briefly discussed on the basis of the structural peculiarities of the complex.
