摘要：
A novel double helix coordination polymer, [Cd(2,2'-bpeec)I-2](n) (1) (2,2'-bpeec=3,6-bis[2-(2-pyridyl)ethenyl]-9-ethylcarbazole) has been prepared and characterized by elemental analyses, IR and luminescence spectra, single crystal X-ray diffraction. Complex 1 crystallizes in the space group P2(1)/c with a=8.444(2), b=23.126(4), c=14.156(2), beta=97.927(2), Z=4, V=2737.8(7) angstrom(3), mu = 3.073 mm(-1). The 2D framework of the title compound is formed by C-H...I hydrogen bonds and pi-pi interactions. The solid-state fluorescent analyses show that the compound exhibits a broad emission band at 547 nm. (c) 2005 Elsevier B.V. All rights reserved.
