Abstract

Abstract: A novel imidazole derivative with π-conjugated system, 1-[trans-4-(4-diethylaminostyryl)phenyl] imidazole(L) and its complex, CoL₄(SCN)₂, were prepared. The structure of the complex was determined by single crystal X-ray diffraction analysis. The crystal is of orthorhombic system, space group P1 with a=0.931 7(3) nm, b=1.275 3(4) nm, c=1.669 1(5) nm, α=89.521(5)°, β=84.591(5)°, γ=80.052(5)°, V=1.944 6(11) nm³, Z=1, μ=0.329 mm^-1, D_c=1.234 Mg/m³, F(000)=765, R₁=0.060 1, wR=0.138 1, GOF=1.030. In the molecular structure of Co(SCN)₂L₄, Co^Ⅱ atom is six coordinated by four N atoms of the ligands(L) and two N atoms of thiocyanate to form an octahedral geometry. The untypical hydrogen bonds and π-π stacking interaction lead to three-dimensional supramolecular formation. The optical properties were experimentally studied.
