OtherCpds =Thiirane ,1,3,5-Trithiane ,Triazacylononane 1,4,7-Trithiacyclononane, also called 9-ane-S3, is the
heterocyclic compound with the formula (CH2CH2S)3. This cyclicthioether is most often encountered as atridentate ligand incoordination chemistry .9-ane-S3 forms complexes with many metal ions, including those considered hard, such as copper(II) and iron(II).
