摘要：
A novel Cu(II)-2,2′-bipy-supported (bipy = bipyridine) mixed valence decatungstate, [Cu(2,2′-bipy)2]2Na2W6VW4VIO30·2H2O 1, has been synthesized and structurally characterized by X-ray analysis. The crystal of 1 is of triclinic, space group P1 with a = 10.9393(10), b = 12.0492(2), c = 12.3783(2) , α = 80.631(10), β = 70.226(10), γ = 72.329(9)°, V = 1459.64(4) 3, Z = 1, Dc = 3.582 g/cm3, F(000) = 1404, R = 0.0553 and wR = 0.1242 for 4607 observed reflections (I > 2σ(I)). The EPR spectrum of 1 indicates that its unpaired electrons are placed in the dx2-y2 orbital of the ground state of CuII. Furthermore, compound 1 shows an antiferromagnetic interaction.
