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

The tripodal character of the title compound, C(33)H(30)N(10)S(3), 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⋯S distance of 4.320 (7) Å. 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)Å. In the crystal, mol­ecules are joined into a three-dimensional supra­molecular network via effective π–π stacking between adjacent heterocycles [centroid–centroid distances of 3.700 (3)–4.118 (4) Å between adjacent inter­layer pyrimidine rings and 3.676 (4) Å between the pyridine rings].
