Abstract:
In this paper, treatment of N-ethyl-benzo[f]quinolium (ebq) iodide and CuI with excess KI afforded an unusual coordination polymer [(ebq)2(Cu3I4)(CuI2)]n (1). 1 crystallizes in tetragonal system, space group P4(2)bc with cell parameters of a = 23.2040 ( 6 ) Å, c = 6.7393 ( 3 ) Å, V = 3628.6 ( 2 ) Å3, Z = 8, Dc = 2.622 g / c3, R1 = 0.0447 and w R2 = 0.0974. A highly interesting feature of 1 is its presence of mixed types of chains [ ( Cu3 I4 )n- and ( CuI2 )n- chain] in one crystal lattice based on supramolecular self-assembly directed by cations. The infinite chains ( Cu3 I4 )n- and ( CuI2 )n- in 1 could be described as the edge-sharing arrangement of CuI4 tetrahedron. Furthermore, IR, EA, UV-Vis, thermal analysis and optical limiting measurements were adopted to characterize polymer 1. The optical limiting experiment shows that the present polymer exhibits a large optical limiting capacity. © 2006 Elsevier Inc. All rights reserved.
