Abstract

2,4,6-Trimercapto-s-triazine, trisodium salt (ideally, Na3S3C3N3·9H2O), also known as TMT-55, is a white powder that is used to precipitate heavy metals from contaminated waters. Chemical analyses confirmed the nominal composition. TMT-55 crystals are uniaxial negative with indices of refraction (25 °C) of nε=1.520 and nω=1.675. The structure was determined by single-crystal methods at 25 and −110 °C. A powder pattern was determined and compared to a simulated pattern based on the 25 °C structure data. Crystal data at 25 °C are: R3;Z=6; a=17.600(1) Å and c=9.720(2) Å; V=2607.5(5) Å3; Dx=1.55 g/cm3.
