N2 - A new 14-membered hexazamacrocyclic copper(II) complex [Cu(H2L1)](ClO4)4(L1 = 1,8-bis(2-aminoethyl)- 1,3,6,8,10,13-hexa- azacyclotetradecane) has been prepared by the one-pot reaction of ethylenediamine and formaldehyde in the presence of the Cu(II) ion. The crystal structure of [Cu(H2L1)](ClO4)4 was determined by X-ray diffraction. It crystallizes in the triclinic space group P - 1 with a = 12.118(2) Å, b = 12.438(2) Å, c = 12.466(2) Å, α = 102.26(1)°, β = 112.82(1)°, γ = 111.51(1)°, and Z = 2. The coordination geometry around the copper(II) ions is axially elongated octahedral with four nitrogen atoms of the macrocycle [Cu-N 2.012(7) Å for Cu(1) and 2.013(6) Å for Cu(2), average value] and two oxygen atoms of two ClO4- anions [Cu-O = 2.550 Å for Cu(1) and 2.601(6) Å for Cu(2)]. [CuL2](ClO4)2(L2 = 3,7-bis(2-aminoethyl)-1,3,5,7-tetraazabicyclo[3,3,2]decane) with a novel tetraazabicyclic ligand was obtained from the same reaction system as an additional product. Crystal structure of [CUL2](ClO4)2: monoclinic space group Cc, a = 16.393(3) Å, b = 8.8640(18) Å, c = 13.085(3) Å, β = 105.01(3)°, and Z = 4.
