title: Redetermination of 3-methyl-isoquinoline at 150 K.
abstract: The structure of the title compound, C(19)H(9)O, has been redetermined at 150 K. The redetermination is of significantly higher precision than a previous room-temperature structure [Ribar et al. (1974 ▶). Cryst. Struct. Commun.3, 323-325]. The C-N bond lengths for this redetermination are much closer to those observed in comparable structures, and the orientation of the methyl group with respect to the isoquinoline plane is clarified. Inter-molecular weak C-H⋯N contacts are present in the crystal.
