| Abstract: A new 2D coordination polymer of {[Cu2(BIPA)2(bpe)2]·H2O}n(1) (H2BIPa=5-bromoisophthalic acid and bpe=1,2-bis(4-pyridyl)ethane) has been prepared and characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. The crystal is of triclinic, space group P1 with a=0.951 2(1) nm, b=1.011 5(1) nm, c=1.170 8(2) nm, α=75.042(2)°, β=76.605(3)°, γ=70.640(2)°, V=1.013 5(3) nm3, Dc=1.638 g·cm-3, Z=1, F(000)=500, Goof=1.022, R1=0.052 7, wR2=0.114 9. Complex 1 consists of one-dimensional [Cu(BIPA)]n chains that are further bridged by trans-bpe into a two-dimensional layer structure. Magnetic data for 1 show a weak antiferromagnetic interaction between the two Cu(Ⅱ) ions with J=-1.54 cm-1. CCDC: 785745. |
