2-Chloro-6,6-dimethyl-5,6-dihydro-indazolo[2,3-c]quinazoline
Abstract:
Two independent but virtually identical mol-ecules comprise the asymmetric unit of the title compound, C(16)H(14)ClN(3). The mol-ecules have a slightly curved shape owing to puckering in the six-membered C(4)N(2) ring; the respective dihedral angles formed between the benzene rings are 12.64 (7) and 11.72 (7)°. In the crystal, layers sustained by a combination of N-H⋯N hydrogen bonding as well as C-H⋯N and C-H⋯π contacts are formed; these stack along [011] and are connected by further C-H⋯π contacts.
