| Abstract: A Cu(Ⅱ) complex [Cu(phen)2Br](H3BTEC) (1, phen=1,10-phenanthroline, H4BTEC=1,2,4,5-benzenete-tracarboxylic acid) was synthesized, and charactered by elemental analysis, IR spectra, UV-Vis spectra, single crystal X-ray diffraction, TG analysis and electrochemical property. The complex crystallizes in triclinic, space group P1 with a=0.971 00(19) nm, b=1.212 0(2) nm, c=1.4290(3) nm; α=102.21(3)°, β=99.57(3)°, γ=107.64(3)°, V=1.51774(7) nm3, Z=2,C34H21BrCuN4O8, Mr=757, Dc=1.656 g·cm-3, μ=2.098 mm-1, F(000)=762, S=1.059, the final R=0.044 9 and wR=0.086 4 for 4 657 observed reflections with I>2σ(I). Two types of one-dimensional chains are demonstrated in the structure. On one hand, the C-H…Br hydrogen bonds and Br…π stacking interactions connect the [Cu(phen)2Br]+ cations into one-dimensional chains; on the other hand, the O-H…O hydrogen bonds aggregate the mono-deprotonated anions into one-dimensional double-layer chains. The two different kinds of chains are further packed into a three-dimensional framework with C-H…O contacts. CCDC: 858948. |
