Synthesis,Crystal Structure and Thermal Stability Study of [Cu2(bpe)X2]n (bpe=1,2‐trans‐bi(4‐pyridyl)ethene,X=Cl,Br, I)

A series of copper(I) halide complexes bridged by bpe (bpe=1,2‐trans‐bi(4‐pyridyl)ethene), [Cu₂(bpe)Cl₂]_n ( 1 ), [Cu₂(bpe)Br₂]_n ( 2 ) and [Cu₂(bpe)I₂]_n ( 3 ) were successfully synthesized and complex 1 has been structurally characterized by a single crystal X‐ray diffraction method. Crystal data for 1 are monoclinic, space group P2(1)/c, a=0.3788(8) nm, b=1.5059(3) nm, c=1.0875(2) nm, β=96.262(4) °, V=0.6165(2) nm³, Z=2, S=1.002, final R indices [I>2δ(I)] R₁=0.0288, wR₂=0.0579, R index (all data) R₁=0.0509, wR₂=0.0615. Elemental analyses and IR spectra reveal that the complexes are of isomorphic compounds. In addition, thermogravimetric analyses were also applied to research of the thermal stability of the title complexes.
