Abstract
In the title compound, C13H12ClN5, which is a derivative of the antitumor agent pazopanib {systematic name: 5-[[4-[(2,3-dimethyl-2H-indazol-6-yl)methylamino]-2-pyrimidinyl]amino]-2-methylbenzolsulfonamide}, the indazole and pyrimidine fragments form a dihedral angle of 62.63 (5)°. In the crystal, pairs of molecules related by twofold rotational symmetry are linked into dimers through π–π interactions between the indazole ring systems [centroid–centroid distance = 3.720 (2) Å]. Weak intermolecular C—H⋯N hydrogen bonds further assemble these dimers into columns propagated in [001].

C13H12ClN5, which is a derivative of the antitumor agent pazopanib {systematic name: 5-[[4-[(2,3dimethyl-2H-indazol-6-yl)methylamino]-2-pyrimidinyl]amino]-2-methylbenzolsulfonamide}, the indazole and pyrimidine fragments form a dihedral angle of 62.63 (5)
Pairs of molecules related by twofold rotational symmetry are linked into dimers through – interactions between the indazole ring systems [centroid–centroid distance = 3.720 (2) A ]
R-factors based on F2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger
