Synthesis and characterization of Cu(bpe)(ddc)[bpe=l,2-bis(4-pyridyl)ethane,H_2ddc=1,10-decanedicarboxylic acid]

摘要

A new 2D structure,Cu(bpe)(ddc)was synthesized by a reaction of hydrated cupric nitrate,1,2-bis(4-pyridyl)ethane(bpe),1,10-decanedicarboxylic acid(H_2ddc)and triethylamine(tea)via a room temperature diffusion method.The compound with chemical formula C_(24)H_(32)N_2CuO_4 crystallizes in triclinic space group P1,a=7.944(3)A,b=8.714(3)A,c=9.366(3)A,alpha=64.55(3)deg ,beta=86.72(2)deg ,gamma=73.74(3)deg ,V=560.5(3)A~3 and Z=1.Within the structure,each copper forms four equatorial bonds with two ddc and two axial bonds with two bpe to give rise to a distorted octahedron.The Cu-ddc connections generate a ID zigzag chain.The chains are further connected via bpe nitrogen at Cu axial positions to result in a 2D layered structure.
