3,14-Dimethyl-2,6,13,17-tetraazatricyclo[16.4.0.07,12]docosane–(naphthalen-1-yl)methanol (1/2)

In the title co-crystal, C20H40N4·2C11H10O, the macrocycle is generated by a crystallographic inversion centre. The N atoms show a pyramidal coordination, and the cyclohexane ring that is fused to the 14-membered C10N4 ring exists in a chair conformation, whereas the methyl substituent occupies an axial site. The (naphthalen-1-yl)methanol molecule forms an O—H...N hydrogen bond to a cyclam N atom. The mean-square-plane passing through the 14-membered ring is approximately coplanar with the naphthalene fused-ring [dihedral angle = 6.6 (1)°].
