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=8Z=8, Dc=2.622g/c3, R1=0.0447R1=0.0447 and wR2=0.0974wR2=0.0974. A highly interesting feature of 1 is its presence of mixed types of chains [(Cu3I4)n- and (CuI2)n- chain] in one crystal lattice based on supramolecular self-assembly directed by cations. The infinite chains (Cu3I4)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.
