Copper(I) Sulfamate P-Complexes : Synthesis and Crystal Structure of [{CH2=CHCH2-)2N-CHO}Cu(NH2SO3)(H2O)] Compound

By alternating-current electrochemical synthesis, the crystalline complex [{CH2=CHCH2-)2 N-CHO}Cu(NH2SO3)(H2O)] (I) has been obtained, using copper(II) sulfamate and diallylformamide (DAFA) in water-methanolic solution and copper-wire electrodes. The single crystal of the compound was X-ray structurally characterized. The Cu atom possesses trigonal pyramidal coordination, formed by nitrogen atom of sulfamate anion and two C=C bonds of the same DAFA molecule at the equatorial plane and the oxygen atom of H2O molecule at apical position. Hydrogen contacts for the most part by (N)H…O and (Ow)H…O bonds of 1,98(3)-2,24(2) A connect separate moieties of the mononuclear complex into a three-dimensional framework. The effective atomic charges in I are calculated.
