      Abstract: The synthesis and crystal structure of   [tris(2-aminoethyl)amineH4]2CuCl10·2H2O, C12H48Cl10CuN8O2, are   reported. Crystals of the compound are triclinic, P1̄, with a =   8.317(1) Å, b = 9.506(1) Å, c = 11.450(1) Å, α = 94.43(1)°, β =   103.29(1)°, and γ = 114.04(1)° (Z = 1). The structure contains   isolated CuCl64- anions, with Cu−Cl(1) = 2.251(1), Cu−Cl(2) =   2.361(1), and Cu−Cl(3) = 3.105(1)Å. The g values obtained from   the EPR spectrum of the powder are g1 = 2.05, g2 = 2.08, and g3 =   2.29. These values are consistent with an elongated octahedral   symmetry with a slightly rhombic distortion. The vibrational   spectra of the CuCl64- anion are assigned in D2h symmetry.
