Synthesis and X-ray Crystal Structure of a New Molecular Clip

The synthesis and X-ray crystal structure of a new molecular clip 2 was reported. It (C24H24N4O2, Mr = 400.47) crystallizes in the space group C2/c with a = 15.587(2), b = 8.5805(12), c = 15.259(2) , β = 102.448(3)°, V = 1992.9 (5) 3, Z = 4, Dc = 1.335 g/cm3, μ = 0.087 mm-1 and F(000) = 848. It remains monomeric in the crystal and a tape-like structure is formed in the crystal structure of molecular clip. The most unusual structural feature of 2 is the boat conformation of its cyclohexyl ring imposed by the ring fusion at C(9)-C(9a).
