Abstract
The mixed-valence Cu3Cl4 · 2C3N3(OC3H5)3 π-complex (I) is synthesized from 2,4,6-triallyloxy-1,3,5-triazine (L) and copper(II) chloride by the alternating-current electrochemical method in an ethanolic solution. Single crystals of complex I are studied by X-ray diffraction analysis: space group I41/a, a = 25.39(8), c = 10.14(6) Å, V = 6537(48) Å3, Z = 8, R = 0.0814. The copper(I) and chlorine atoms form unique cyclic tetramers Cu4Cl4. The coordination sphere of each copper(I) atom includes the C=C bond of the allyl group of the ligand molecule L in addition to the two bridging chlorine atoms. Two nearest triazine rings are coordinated through the nitrogen atoms to the copper(II) atoms, whose environment is completed to a square with two chlorine atoms. An intricate three-dimensional structure is formed due to the μ4-bridging function of the cupro(I) tetramer and the μ2-bridging function of the ligand molecule L.
