Tris[2-(2H-indazol-2-yl)eth-yl]amine.
The title tertiary amine, C(27)H(27)N(7), a potential tripodal ligand for coordination chemistry, crystallizes with the central N atom located on a threefold axis of a trigonal cell. The gauche conformation of the N(amime)-CH(2)-CH(2)-N(indazole) chain [torsion angle = -64.2 (2)°] places the pendant 2H-indazole heterocycles surrounding the symmetry axis, affording a claw-like shaped mol-ecule. Two symmetry-related indazole planes in the mol-ecule make an acute angle of 60.39 (4)°. The lone pair of the tertiary N atom is located inside the cavity, and should thus be inactive (as a ligand). In the crystal, neither significant π-π nor C-H⋯π inter-actions between molecules are found.
