PbS microcrystals with a magic‐square‐shaped structure were successfully fabricated via a simple hydrothermal route, employing (CH 3 COO) 2 Pb and Na 2 S 2 O 3 as the lead and sulfur source without the assistance of any surfactant or template. S 2 O 3 2‐ ions acted not only a supplier of S 2‐ ions but also a coordinating reagent. The formation of the above morphology was the direct result of the coordination between thiosulfate ions and lead ions. Researches indicated that the different synthetic approach could influence the morphology of the final product. A possible formation mechanism was suggested. (© 2006 WILEY‐VCH Verlag GmbH & Co.
