Synthesis and Crystal Structures of Complexes of Zinc, Silver, Copper Assembled by Uniconazole

Abstract

Three coordination polymers [ZnL4Cl2]n(1), [(AgL2·NO3)2]n(2), [CuL4·2NO3]n(3) (L = uniconazole) have been synthesised and structurally characterized by element analysis, infrared spectra and X-ray crystal diffraction. Complex 1 is the triclinic system, space group P-1 with a = 8.9407(10) A, b = 13.2994(15) A, c = 14.9242(17) A, α = 93.8180(10)°, β = 99.0250(10)°, γ = 104.7690(10)°, V = 1684.1(3) A3. Complex 2 is the Triclinic system, space group P-1 with a = 8.997(3) A, b = 16.941(5) A, c = 24.113(7) A, α = 89.182(4)°, β = 86.440(4)°, γ = 86.440(4)°, V = 3483.0(19) A3. Complex 3 is the triclinic system, space group P-1 with a = 8.7387(5) A, b = 13.4087(8) A, c = 15.4353(9) A, α = 87.8870(10)°, β = 80.7150(10)°, γ = 71.3930(10)°, V = 1691.42(17) A3. In 1 and 3, Each six-coordinated Zn(II), Cu(II) ions adopts a distorted octahedral geometry. 1 and 3 was linked into a one dimensional chain by intermolecular hydrogen bonds. But in 2, each Ag(I) ion is two-coordinated in a linear mode. Althought there is many intermolecular hydrogen bonds, but the complex is zero dimensional. Three new coordination polymers [ZnL4Cl2]n(1), [(AgL2·NO3)2]n(2), [CuL4·2NO3]n(3) (L = uniconazole) have been synthesised and structurally characterized by element analysis, infrared spectra and X-ray crystal diffraction.
