Tris[2-(2H-indazol-2-yl)eth-yl]amine.

ABSTRACT: 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 ?-? nor C-H?? inter-actions between molecules are found.

Tris{2-[(3-thien-yl)methyl-idene-amino]-eth-yl}amine.

Project description: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.

Tris{2-[4-(2-pyrid-yl)pyrimidin-2-ylsulfan-yl]eth-yl}amine.

Project description: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].

Project description:The indazole ring system of the title compound, C19H21N3O3S, is almost planar (r.m.s. deviation = 0.0192?Å) and forms dihedral angles of 77.99?(15) and 83.9?(3)° with the benzene ring and allyl group, respectively. In the crystal, centrosymmetrically related mol-ecules are connected by pairs of N-H?O hydrogen bonds into dimers, which are further linked by C-H?O hydrogen bonds, forming columns parallel to the b axis.

N-(2-Chloro-pyrimidin-4-yl)-N,2-di-methyl-2H-indazol-6-amine.

Project description:In the title compound, C(13)H(12)ClN(5), which is a derivative of the anti-tumor agent pazopanib {systematic name: 5-[[4-[(2,3-di-methyl-2H-indazol-6-yl)methylamino]-2-pyrimidinyl]amino]-2-methylbenzolsulfonamide}, the indazole and pyrim-idine fragments form a dihedral angle of 62.63?(5)°. In the crystal, pairs of mol-ecules related by twofold rotational symmetry are linked into dimers through ?-? inter-actions between the indazole ring systems [centroid-centroid distance = 3.720?(2)?Å]. Weak inter-molecular C-H?N hydrogen bonds further assemble these dimers into columns propagated in [001].

1-(Furan-2-yl)-2-(2H-indazol-2-yl)ethanone.

Project description:The asymmetric unit of the title compound, C13H10N2O2, contains two crystallographically independent mol-ecules (A and B). The indazole ring systems are approximately planar [maximum deviations = 0.0037 (15) and -0.0198 (15) Å], and their mean planes are oriented at 80.10 (5) and 65.97 (4)° with respect to the furan rings in mol-ecules A and B, respectively. In the crystal, pairs of C-H⋯N hydrogen bonds link the B mol-ecules, forming inversion dimers. These dimers are bridged by the A mol-ecules via C-H⋯O hydrogen bonds, forming sheets parallel to (011). There are also C-H⋯π inter-actions present, and π-π inter-actions between neighbouring furan and the indazole rings [centroid-centroid distance = 3.8708 (9) Å] of inversion-related mol-ecules, forming a three-dimensional structure.
