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 f
consistent with the proposed structure, notably the return to C, symmetry. The addition of a second rhodium dicarbonyl fragment and formation of 6 causes this Soret-like band to shift still further to the red, to about 500 nm. The structures of 5b-CI and 6a (Fig. 1 and2, respectively) are similar to
