1, and cis – anti – cis -dicyclohexyl-18-crown-6/ N,N ′-diphenylthiourea, 2, both of 1:2 ratio, exhibit one-dimensional (chain) and zero-dimensional (molecular complex) structures correspondingly. The crystals of 1 are monoclinic, space group P2 1 /c , a =13.142(2), b =20.367(5), c =12.090(3) A, β =92.32(1)°, V =3233.4(1) A 3 , Z =4. The crystals of 2 are triclinic, space group P-1 , a =9.958(2),
