In the title co-crystal, C(20)H(40)N(4)·2C(11)H(10)O, the macrocycle is generated by a crystallographic inversion centre. The N atoms show a pyramidal coordination, and the cyclo-hexane ring that is fused to the 14-membered C(10)N(4) ring exists in a chair conformation, whereas the methyl substituent occupies an axial site. The (naphthalen-1-yl)methanol mol-ecule forms an O-H⋯N hydrogen bond to...

In the title compound, C(32)H(28)N(2)O(2), the pyrrolidine ring adopts an envelope conformation, whereas the cyclo-hexa-none ring in the tetra-hydro-naphthalene fused-ring system adopts a half-chair conformation. The oxindole ring system is oriented at an angle of 48.2 (1)° with respect to the naphthyl ring system. An intra-molecular C-H⋯O close contact is observed. In the crystal, mol-ecules a...
