Abstract: Two complexes of α-methacrylate copper(Ⅱ) with imidazole, Cu[CH2=C(CH3)COO]2· (imH)2(1) and Cu 2[CH2C(CH3)COO]4(imH)2(2) were prepared and characterized. The single crystal X-ray diffraction study of complex 1 showed that the copper(Ⅱ) atom in the symmetric centre of the square planar environment was coordinated by two monodentate α methacrylate groups and two imidazole ligands that were in trans position with each other. Each molecular unit is linked with four neighbouring units by means of hydrogen bond interactions, forming a two-dimensional supermolecular compound( dN…O =0.278 1 nm). Complex 1 crystallizes in monoclinic, space group P21/n with a =1.023 94(12) nm, b =0.842 94(8) nm, c =1.079 35(10) nm, β=117.231(7)°, Z =2. The forming mechanism of the complexes was discussed.
