The perovskite oxide LaCoO<sub>3</sub> was synthesized by three different preparative methods <i>i.e.</i>, the calcination of a mixture of La<sub>2</sub>O<sub>3</sub> and CoO (La–Co–O) and pyrolysis of a co-precipitated precursor (La–Co–ox), La<sub>2</sub> (C<sub>2</sub>O<sub>4</sub>)<sub>3</sub> · <i>x</i>H<sub>2</sub>O + CoC<sub>2</sub>O<sub>4</sub> · <i>y</i>H<sub>2</sub>O, and a heteronuclear complex (La–Co–CN), La[Co(CN)<sub>6</sub>] · 5H<sub>2</sub>O. The obtained powders were characterized by thermogravimetric analysis, infrared spectroscopy, powder X-ray diffraction, scanning electron microscopy and specific surface area measurements. The formation of LaCoO<sub>3</sub> single phase is clearly recognized for La–Co–O, La–Co–ox and La–Co–CN at temperatures above 1000, 1200 and 600 °C, respectively. The nano-sized LaCoO<sub>3</sub> powder was obtained at low temperatures by pyrolysis of La–Co–CN. The mean particle diameter of La–Co–CN calcined at 600 °C for 2 h was 72 nm.
