A novel imidazole derivative with functional group and π-conjugated system, 1- [trans-4-(4-diethylaminostyryl)phenyl]imidazole (abbreviated as L), and its CoII complex (CoCl2L4)2 (Co2C168H184N24Cl4, Mr = 2799.05 ) have been synthesized and the crystal structure of the latter was determined by X-ray diffraction. The crystal is of triclinic, space group P with a = 8.823(3), b = 18.799(7), c = 23.065(9) (A), α = 77.349(6), β = 83.128(7), γ = 80.942(3)°,V = 3671.5(12)(A)3, Z = 1, Dc = 1.266 g/cm3, μ = 0.361 mm-1, F(000) = 1482, the final R = 0.0587 and Wr = 0.1284 for 6562 observed reflections with Ⅰ ＞ 2б(Ⅰ). In the molecular structure of (CoCl2L4)2, there are two crystallographically unique units. The CoII atoms are six-coordinated by four N atoms from four imidazole ligands (L) and two Cl atoms to form a distorted octahedral geometry. The optical properties of complex (CoCl2L4)2 have been experimentally studied.
