Abstract
Single crystal X-ray analysis of a 1 : 2 complex between the dinaphthopyridino-l8-crown-6 host (1) and acetonitrile is reported. Crystals of the complex are monoclinic,P21/c witha = 12.178(5),b = 8.186(1),c = 30.873(1) Å, β = 96.86(1)°, andD c = 1.25 g cm−3 forZ = 4. The host molecule reveals an approximate mirror symmetry and exists in a so-called ‘dentist's chair’ conformation. One of the acetonitrile guest molecules is involved in possible weak interactions to two oxygen atoms of the host macroring, while the other fills free lattice space only.
