✦ Synopsis

The preparation of nanocrystalline Cu 2 SnS 3 at synthetic conditions of low temperature (<1803C) was 5rst reported. Nanocrystalline Cu 2 SnS 3 was directly synthesized from the reaction of CuCl 2 ' 2H 2 O with elemental tin and sulfur through a solvothermal process in ethylenediamine at 140+1803C for 15 h. X-ray di4raction (XRD) patterns, transmission electron microscope (TEM) images, and X-ray photoelectron spectra (XPS) were used to characterize the products. The mechanism of the formation of the Cu 2 SnS 3 nanocrystals in the solvothermal process was proposed. The UV+vis absorption spectroscopy and the electric conductivity of products were also studied.

Single crystals of SnS 2 were intercalated with ethylenediamine (en) and propylenediamine (pn) by direct reaction. The resulting novel compounds were examined by di4erent techniques including XRD, XPS, a.c. impedance, TG, and TPD measurements. The observed lattice expansion for both compounds, ca. 3

## Abstract We report an ethanol‐mediated surfactant‐free solvothermal synthesis of phase‐pure __Pnmm__ FeSb~2~ nanocrystals with an average size of 40 nm. The capping free growth of the nanocrystals resulted in the formation of inherent orthorhombic shapes. The nanocrystals were densified by spark
