Abstract

The title compound, C(21)H(24)N(4)S(3), is a tripodal Schiff base that was obtained from the reaction of tris-(2-amino-eth-yl)amine (tren) and thio-phene-3-carbaldehyde. The compound forms a cavity with approximate C3 symmetry. One of the thio-phene units is disordered in a 0.764 (2):0.236 (2) ratio. In the crystal, the three thio-phene ligands are involved in intra-molecular C-H⋯π inter-actions and the mol-ecules are connected by C-H⋯N inter-actions, forming hydrogen-bonded chains.
