| Abstract: A molecular bowl with barium ion covering one portal of decamethylcucurbit[5]uril as a ‘metal-ion-bottom’ has been synthesized. The structure of the molecular bowl has been confirmed by the single crystal X-ray diffraction determination. It belongs to orthorhombic with space group of
Pna21. The crystal unit cell parameters are: a=3.210 8(6) nm, b=1.474 2(3) nm, c=1.151 6(2) nm, and V=5.450 9(18)
nm3, Dc=1.677 Mg·m-3, Z=4, F(000)=2 832, R=0.055 1, wR=0.156 8. CCDC: 290552. |
