REACTION OF BIS(β-ALANINATO)COPPER(II) WITH FORMALDEHYDE: X-RAY CRYSTAL STRUCTURE OF AQUABIS(N,N-DIMETHYL-β-ALANINATO)COPPER(II) HEXAHYDRATE

Abstract

The reaction of bis(β-alaninato)copper(II) with formaldehyde results in the formation of blue crystals of aquabis(N,N-dimethyl-β-alaninato)copper(II) hexahydrate, [Cu(C₅H₁₀NO₂)₂(OH₂)].6H₂O which crystallize in the monoclinic space group C2/c with unit cell dimensions a = 20.799(2), b = 8.112(1), c = 23.639(1)Å, β = 96.50(1)° and Z = 8. The structure has been refined to final R = 0.047 and R_w = 0.053 for 1690 reflections with I ≥ 2.55σ(I).
