Popis:	The preparations of solid-state benzonitrile complexes of two oligoaryl-condensed crown hosts are described and their crystal structures are reported. Benzo-di[(2,3)naphtho]-(2,6)pyridino-21-crown-7 (1) forms a crystalline 1:3 (host:guest) complex (1a) while benzo-di[(1,4)benzeno]-(2,6)pyridino-25-crown-7 (2) forms a 2:1 crystalline complex (2a) with PhCN. Crystal data: 1a [P 1, a = 13.455(3), b = 15.313(2), c = 13.371(4) A, α = 103.75(2), β = 109.00(2), γ = 103.63(2)°, Z = 2], 2a [C2/c,a = 37.105, b = 17.410(8), c = 8.598(3) A. β = 90.89(2)°, Z = 4]. Both compounds are lattice-type complexes showing no significant host-guest contacts. The crystal structures are stabilized by dipole-dipole, stacking and van-der-Waals interactions.
