Abstract:
The tripodal character of the title compound, C(33)H(30)N(10)S(3), arises from the three thio-ether 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, mol-ecules are joined into a three-dimensional supra-molecular network via effective π-π stacking between adjacent heterocycles [centroid-centroid distances of 3.700 (3)-4.118 (4) Å between adjacent inter-layer pyrimidine rings and 3.676 (4) Å between the pyridine rings].
