摘　　要：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=3.2108(6) nm, b=1.4742(3) nm, c=1.1516(2) nm, and V=5.4509(18) nm3, Dc=1.677 Mg·m-3, Z=4, F(000)= 2832, R=0.0551, wR=0.1568. CCDC: 290552.A molecular bowl with barium ion covering one portal of decamethylcucurbit[5]uril as a ＇metal-ionbottom＇ has been synthesized.
