The nanocrystalline copper (II) complex with hippuric acid have been synthesized by solvent-free Mechano chemical synthesis. Copper (II) hippurate complex was characterized by UV-Vis spectra, fourier transform Infra red spectra, powder X-ray diffraction, High resolution scanning electron microscopic analysis, Transmission electron microscopic analysis, Thermal analysis, and Elemental analysis. The process presented here is operationally simple, environmentally benign and affords excellent yields without the need for any solvent.
