N2  - Two new compounds with a tripodal ligand architecture and with the potential to act as heptadentate N4S3 donor ligands are reported. H3S3trac (4,4&#8242;,4&#8242;&#8242;-&#91;nitrilotris(ethyleneimino)&#93;tris(pent-3-ene-2-thione)) is prepared by the reaction of acetylacetone with tren (tris(2-aminoethyl)amine), followed by treatment with P2S5. H3trimda (3,3&#8242;,3&#8242;&#8242;-&#91;nitrilotris(ethyleneimino)&#93;tris(2-phenylpropenethial)) is prepared by the reaction of 4-phenyl-1,2-dithiolium perchlorate with tren. A crystal structure of H3S3trac shows it to be monoclinic, P 21/c, a 11&#183;443(7), b 11&#183;7757(14), c 19&#183;285(3) &#197;, &#946; 106&#183;68(2)&#176;, Z 4, R 0&#183;0454, &#x03C9;R2 0&#183;1108 for 1618 observed reflections (I &#62; 3&#963;(I)). 1H and 13C &#123; 1H&#125; n.m.r. data for H3S3trac and H3trimda, and the crystal structure of H3S3trac are consistent with the compounds existing in the enamino thione tautomer.
