Tris{2-[4-(2-pyridyl)pyrimidin-2-ylsulfanyl]ethyl}amine

The tripodal character of the title compound, C33H30N10S3, arises from the three thioether arms surrounding a central amine N atom. The three arms have approximately the same conformation but distinct geometries in a trans-trans-cis conformation, resulting in a short pyridine-sulfanyl N center dot center dot center dot S distance of 4.320 (7) angstrom. The distances of the central N atom to the N atoms of three pyridine rings in the arms are 8.305 ( 7), 8.032 (7) and 5.076 (9) angstrom. In the crystal, molecules are joined into a three-dimensional supramolecular network via effective pi-pi stacking between adjacent heterocycles [centroid-centroid distances of 3.700 (3)-4.118 (4) angstrom between adjacent interlayer pyrimidine rings and 3.676 (4) angstrom between the pyridine rings].
