Hydrogen-bonded 1D and 2D Assemblies of Tetra- iso-butyl-resorcin4arene in the Crystalline State

摘要

X-ray crystal structures of co-crystals involving tetra-iso-butyl-resorcin[4]arene 1 with both acetone and acetonitrile solvents were reported. The component 1(2(CH3)2CO 2 assembles such that the resorcin[4]arene adopts a C2v conformation and the acetone serves as hydrogen bond acceptors, forming a 1D hydrogen-bonded polymer. 2 (C50H68O10) crystallizes in the triclinic, space group P with a = 10.0440(7), b = 13.7498(9), c = 17.6374(12) (A), α = 77.726(2), β = 86.733(2), γ = 88.634(2)°, V = 2376.1(3) (A)3, Dc = 1.159 g/cm3, and Z = 2. The assembly process of component 1(2CH3CN(H2O 3 yields a 2D hydrogen-bonded polymer formed by intermolecular hydrogen bonds between resorcin[4]arene and water molecules. In the case of component 3, the acetonitrile molecule serves as guest inside the bowl of resorcin[4]arene host. 3 (C48H64N2O9) crystallizes in the monoclinic, space group P2 with a = 13.7570(18), b = 9.0961(12), c = 19.453(3) (A), β = 103.017(3)°, V = 2371.7(5) (A)3, Dc = 1.138 g/cm3, and Z = 2.
