Tripropylammonium trithiocyanurate

Abstract

In the title compound (systematic name: tripropyl­azanium 2,4,6-tris­ulfanyl­idene­cyclo­hexan-1-ide), (C3H7)3HN+·C3H2N3S3 −, one H atom of trithio­cyanuric acid is accepted by tripropyl­amine to form the ammonium ion. Coplanar trithio­cyanurate and tripropyl­ammonium ions [dihedral angle = 82.33 (8)°] form the salt, which is stabilised by various N—H⋯S and N—H⋯N contacts.

The second polymorph of triethylammonium 2,4,6-trisulfanylidene-1,3,5-triazinan-1-ide, C9H18N4S3

“…Two crystallographically independent triethylammonium cations form N-H· · · S hydrogen bonds to yield the stable title structure. Previous articles report the crystal structures of tripropylammonium [2] and triethylammonium [3]. Interestingly, the crystal structure of the title compound has been reported before [3] which is di erent from the structure in this paper.…”

Synthesis and crystal structure of N,N-dimethylformamide solvate of thiocyanuric acid

“…Thiocyanuric acid (TCUA) is very well known to form polymers through extensive hydrogen bonds [7,8,16,18,24]. Here, we were able to prepare a layered, 3D-structure of TCUA with DMF, where the TCUA molecule N-H bonds act as H-bond donors and TCUA molecule C-S bonds and DMF molecule C=O bonds serve as H-bond acceptors.…”

“…The trithiol form (I) is predominant in metal complexes [8][9][10][11]15], whereas the trithione form(II) has been observed to exist in the monolithiated hexamethylphosphoramide complex and in the ammonium salts and solvent adducts of TCUA [7, 8, 12-14, 16-18, 22]. For instance, the triethylammonium salt of TCUA has two polymorphs with 1-D chain structures based on N-H-S and N-H-N hydrogen bonds [16,23]. On the other hand, the tripropylammonium salt of TCUA has a 2-D structure stabilized by N-H-S and N-H-N hydrogen bonds.…”
