Coordination compound hexakis (imidazole) cobalt (Ⅱ) trifluoroacetate , [ Co (Im) 6 ] ·(CF3COO)Z (Im = Imidazole), was synthesized and characterized by means of crystal X-ray diffraction, nuclear magnetic resonance spectroscopy (1H NMR), and Fourier transformation infrared spectrometry (FT-IR). Results indicate that as-synthesized coordinate compound belongs to monoclinic system with space group P21/c. Its cell parameters are α = 1. 086 3 (2)nm, b = 1. 779 0(4) nm, c = 0. 789 38(16) nm, α = 90 °, β = 96.56(3) °, γ = 90 °, V =1. 515 6(5) nm3, Z = 2, Dc = 1. 520 Mg/m3, μ = 0. 654 mm-1, and F (000) = 706. The central ion Co(Ⅱ) assumes a typically centro-symmetric octahedral geometry. In solid state, title coordinate compound forms three-dimensional hydrogen bond networks, which contributes to stabilizing the structure.
