CALVO, VICTOR et al. INFLUENCE OF HYDROGEN BRIDGES ON THE MAGNETIC PROPERTIES OF COPPER(II) BIS(TRIFLUOROACETATE) COMPLEXES. Bol. Soc. Chil. Quím. [online]. 2000, vol.45, n.2, pp.259-268. ISSN 0366-1644.  http://dx.doi.org/10.4067/S0366-16442000000200013.

Copper(II) trifluoroacetate with three coordinated water molecules and two dioxane molecules (1) crystallized as a linear chain surrounded by a net of hydrogen bonds to the dioxane and trifluoroacetate. This complex [Cu(H₂O)₃(OOC-CF₃) ₂]·2(C₄H₈O ₂) crystallizes in the triclinic space group P1 with a = 6.067(1)Å, b = 12.153(3)Å, c = 15.057(3)Å, a= 100.09(2), b= 99.15(2), g= 101.00(2) and Z = 2. The single crystal EPR spectrum of (1) shows to signals (g
