In the mol-ecule of the title compound, C(17)H(18)N(2)O(2), the dihedral angle between the aromatic rings is 74.26 (3)°. The oxime units are oriented at dihedral angles of 7.66 (3) and 33.06 (3)° with respect to the adjacent rings, and they have E configurations about the C=N bonds.
In the title molecular salt, C(9)H(18)NO(+)·Cl(-), the morpholine ring adopts a chair conformation. In the crystal structure, intra-molecular C-H⋯Cl bonds occur and inter-molecular C-H⋯O and C-H⋯Cl hydrogen bonds link the mol-ecules.
In the title compound, C(12)H(18)NO(+)·PF(6) (-), the asymmetric unit consists of two cation-anion pairs. The six F atoms of one anion are disordered over two sets of sites in a 0.592 (6):0.408 (6) ratio. The morpholinium rings adopt chair conformations.
