title: 7-Methoxy-1H-indazole, a new inhibitor of neuronal nitric oxide synthase.
abstract: The crystal structure of 7-methoxy-1H-indazole, C(8)H(8)N(2)O, an inhibitor of nitric oxide synthase, shows that the methoxy group lies in the plane of the indazole system with its methyl group located trans to the indazole N-H group. The crystal packing consists principally of hydrogen-bonded trimers. Intermolecular hydrogen-bonding interactions are formed between the indazole N atoms, with the N-H group as a hydrogen-bond donor and the remaining N atom as an acceptor.
