Mono and trivalent thallium–sulfur interactions and their influence on the formation of nano thallium sulphide: single crystal X-ray structural and spectral studies on thallium(i)/(iii)–cyclohexylpiperazine dithiocarbamates

Tl–S bond distances in (1) are longer than in (2) and hence the greater ease of solvothermal decomposition of (1) to nano Tl4S3 than (2).
